> has bought ineffective products like eye cream based on five-star reviews, including some that appeared fake. Now she only looks at two-, three- and four-star reviews when she shops on Amazon.
My strategy has always been to read the 1-star and 2-star reviews, most recent first, unless there are so few total (e.g. under a dozen) that I may as well just read them all.
Positive reviews, even 4-star and (enough of the) 3-star tend to be useless to me. What I want to know is why people hated the product. If it's exclusively for reasons that don't apply to me or for risks/problems inherent to the type of product, then I have what I need.
Negative reviews are often also where the best referals to alternative products can be. Of course, those have a high enough likelihood of being posted by a shill that one can't assume it's actually better without reading those reviews, too, but it can beat grinding through all of Amazon's search results.
All that said, the worsening counterfeit and delivery situation means I've bought hardly anything in the past year, after a progressive decline in buying the year before.
Often I wish I could just sort by least 1-start reviews or least 1-2-star reviews. Most products you don't need an amazing version, you just need one that isn't crap.
The only problem with this strategy is that competing vendors will start leaving 1 star reviews on reviews of rival products.
That said, I haven't bought much either and switched to vendors that somewhat vouch for their products like Best Buy, Walmart, Monoprice, etc
I’ve started using Walmart.com for just this reason. I no longer trust Amazon. Trust is a hard thing to acquire once it’s lost. After an Amazon Basics usb cable stopped working after a few weeks I don’t even trust Amazon's own products.
I like this method of "selection by rejection". It makes sense. People like stuff for a variety of reasons, what one ought to be looking for is adversarial feedback. But how do you choose which bad reviews to ignore ?
> But how do you choose which bad reviews to ignore ?
Content-free ones like "hated it" or "didn't work" or even "DOA" (and nothing more) can generally be summarily ignored.
Other ones I don't exactly ignore but, perhaps, dismiss, are of the form "it was too complicated for me to use" or "it didn't solve my specific problem". In general, I already know ahead of time what I'm up against in terms of ease of use, problem "fit", or similar issues. However, if not, these comments can, in aggregate, be helpful in setting expectations, just not in rejecting the product.
Another dismissal-worthy category I alluded to are complaints that are generally universal to all products of that type. A trivial, historical example would be complaining about hard drive capacities being advertised in SI units not matching the power-of-2 units displayed by the OS. A more modern example would be external battery pack mAh capacity claims, where it's often the nominal (raw) capacity of the 3.6V internal cells, not the 5V USB output (which isn't 100% efficiently converted), further confounded by the fact that capacity varies widely by discharge rate.
If there's a truly high volume of content, I end up trying to scan for people who have written both lengthier reviews and mention something that sounds like my personal use case. It's time-consuming, unfortunately, and, with today's chance of getting a counterfeit anyway, not even worth it for most of those items.
Years ago, I felt like I could trust that the prices, selection, and quality of items I found on Amazon were relatively predictable. Now that it's a bazaar rather than a store, I can't trust anything and unless I want to get ripped off I have to apply an exhausting level of scrutiny to each item purchased. As a result, I don't shop there nearly as much as I once did.
How is Amazon thriving? I don't get it. Don't other people have the same experience?
I feel the same way about Amazon. What tipped me over the line was a counterfeit pair of Ecco shoes. I mean, seriously? You cannot safely buy air or water filters, SD cards, batteries, and so much more, but you have to even now be super cautious about buying shoes from Amazon? Its just not worth the convenience. It feels almost like an abusive relationship.
I've started experimenting with Walmart to replace lots of the stuff I usually get from Amazon. Unsure about them yet.
Unless Amazon ditches the 3rd party sellers, I won't be back.
The solution doesn't have to be ditching 3rd parties as these can create great shopping value. Amazon should create a hurdle that keeps scammers away. While obvioudly there are better solutions than my off the cuff comment you could for example require a significant deposit for new sellers which is lost on sale of fake goods. Or payment terms are 120 days until you reach X reputation (supplier or item) allowing for full refunds to customers and zero payment to suppliers should fakes show up.
Solution is simple, create a filter to only show items shipped and sold Amazon.com, and never commingle inventory.
But amazon wants to have its cake and eat it too. It wants to offload all that inventory risk into others and it wants its customers to pay the same or more as other retailers who you can trust to not sell counterfeit goods.
A consumer’s only solution is to switch your purchases to actual retailers who are selling goods you can trust.
At the very least, Amazon should mark the commingled vs. non-commingled status for each offer. Right now, you only see this once you hold the item in your hands - if there's a barcode starting with "X" on the package, it's non-commingled AFAIK.
(But I wonder if Amazon actually authenticates X-labeled incoming merchandise, e.g. by requiring a shared secret on the package slip. Otherwise, if an attacker sends in a fake item that's X-labeled as if it came from an honest seller, they would still be able to tank the reputation of the honest seller. Maybe this could even be done from the position of an Amazon customer, i.e. they would apply the fraudulent X-label to a swapped "returned" item. Who would believe the honest seller in this circumstance?)
It used to be you can click "Amazon Prime" and get a reputable seller...but now I guess you gotta click on "Sold by Amazon". I hope they don't commingle Amazon's stuff with 3rd party sellers...
If so...I'm just going to buy name brand items in stores and get a price match.
Third party sellers can also sell directly to Amazon via something called Amazon Vendor Central. Their products will be "Sold by Amazon". I know someone who was accused of selling counterfeit products to Amazon. He has 3 different accounts all hooked up to its own network.
Another Amazon horror story would be I was listening to an Amazon seller podcast. The person being interviewed sold supplements. He said he imported some herbs from South America, picked them up at the airport, dropped them off at the plant with some bottles, got them, and sent them off to Amazon. Nowhere did he mention fda or anything. I'm hoping things are a lot harder now to sell your own private label supplements on Amazon, like requiring GMP certificates or invoices from a credible manufacturer... Or even worse electronics from China that do not have any of the required testing that retail brick and mortar stores require. Or ah maybe the worst story of all. The Amazon seller who sells used bras as new on Amazon. I stopped buying bras on Amazon after I heard that one at an Amazon seller event.
"Dietary supplements" are essentially unregulated. The manufacturer is responsible for doing any quality control/inspections/etc. The FDA might come after you after you sell something, but they do absolutely no verification before. I can't find any evidence that the regulation requires anyone but the manufacturer to do anything and it doesn't seem there is any verification. (in other words, don't trust supplements no matter where you buy them)
On the other hand, all meat that isn't privately sold is required to be inspected before and after slaughter and processing by the USDA. The packing plants have to shut down if there aren't inspectors there.
>I hope they don't commingle Amazon's stuff with 3rd party sellers...
Sorry, but they do. I've sold new stuff on Amazon. I ship it out to their warehouses. When you look at the product, you will see my price amongst the various Prime sellers. However, when you ship something new to Amazon, they ask whether it is OK to comingle your product with Amazon's. There's no good reason to say "No". So when you buy from me, you could be getting the one owned by Amazon, and vice versa.
Anker usually are the only sellers on their item listings so I buy electronics from them on Amazon because their items won't be conmingled. Otherwise, I go to Best Buy and pay the premium for the quality control.
People who get what they ordered aren't newsworthy? I buy all manner of stuff from amazon and haven't had much trouble. One time I got something that wasn't quite right (my two pack was missing one) but they immediately refunded the cost and I got to keep it. Reports of fraud have been somewhat concerning, but I see no reason to change anything. Their experiments with their own courier delivery service have been far more disruptive, but the great AI in the cloud has learned my address work best with UPS and everything is back on track.
The vast majority of people still think it's the old days. Until all of seller fraud at Amazon hits the mainstream news, they will still believe that Amazon is a land of legitimate abundance and good deals.
Same here. I get really stressed when I go on Amazon because there is so much junk there. I also used to buy from Newegg a lot but since they started selling from third party suppliers it's also a mess.
Nowadays I feel almsot more confident to buy on ebay from sellers that have thousands of ratings with a high positive percentage.
Amazon is problematic simply because they refuse to let you filter searches, and stop the ridiculous co-mingling practices.
Newegg so far hasn't done either of those things, and I simply select "Sold by Newegg" as the only options I'll consider when looking.
I also get annoyed at every damn e-store now being a giant import of some silly bazaar database - but at least Newegg still gives you the ability to ignore it.
Yes, my first online purchases were from ebay, I then switched to amazon but now I mostly buy on ebay again.
I trust its ratings more than amazon's and also ebay feels less creepy to me as a company.
They do, however it is easy to miss the 'bulk' rush. Which is to say that the bulk of the people using Amazon aren't particularly careful so they just click the 'buy it' link and never think twice about it.
As a result the services suffer, and they will continue to do so which then opens up a niche for a new seller to come along. Ebay has suffered the same cyle.
My brother ordered a 6 pack of tea boxes, seller "accidentally" sent 1. His reviews were full of the same complaint but I thought Amazon a2z guarantee was still around and would fix it. It wasn't, I couldn't even contact Amazon about it. All the order help would lead to emailing the seller.
As somebody selling on Amazon MWS, this might be entirely Amazon's item matching issue - when you are uploading your item feed to Amazon, items on your feed are mapped automatically to Amazon's ASINs (basically their own IDs), and that matching often ignores when you specified pack quantity. I.e. sometimes your 6-pack gets matched as a single item and sometimes a single item gets matched as a 6-pack. They have that issue ~8 years already; I guess to them it's more important to invest elsewhere than to better algorithms...
It's not hard or unreasonable to restrict yourself to items shipped and sold by Amazon, and to do a little extra searching for things outside that bubble. (usually just fakespot and reading a few good and bad reviews)
I always leave a review with pictures and as much info as I can if the product is shit and not what I expected or what the reviews suggested to help the next folks. I actually bought a jump rope on Amazon that was "Amazon's Choice" and it turned out to be crap. I found that exact same jump rope at Walmart for $4.99 instead of $25 on Amazon and went to war with the seller.
He emailed me repeatedly offering refunds or a new rope, etc to change my review. This only encouraged me to post more pictures and comparisons. Eventually, they just added like 20 reviews to push mine down.
I don't buy anything on AMZN anymore unless it is something where I know I'm getting the real thing at a good price. Typically you can find those cheap Chinese items on AMZN for a lot less at Walmart or a local store. It's a shame that AMZN isn't able to police their reviews culling all the fakery.
The seller fraud started happening when Amazon let international vendors on the platform so they could compete with Alibaba. It's virtually impossible for Amazon to police all their international vendors given how hard things like verification are internationally. Even when they do ban a vendor, it's very easy for them to pop up again under a different name.
amazon was always the wild west. since 2009 when I started to use amazon heavily I remember having to always police myself to never buy from items without the "sold by amazon" note.
it has nothing to do with evil foreigners or going down to alibaba level. amazom was always the alibaba of the US.
since 2009 when I started to use amazon heavily I remember having to always police myself to never buy from items without the "sold by amazon" note.
What you've missed is that ever since Amazon added "fulfilled by Amazon" what "sold by Amazon" means is only "pulled from stock in an Amazon warehouse, with that stock coming from both Amazon wholesale orders and stock shipped in by third party sellers." Basically commingling of stock means that "Sold by Amazon" is entirely an accounting function now and says nothing about the physical products or their origin.
I have sold on Amazon via FBA. Everything you say is true. If I ship a new item to Amazon's warehouses, I go through a step in the process where I explicitly give Amazon permission to comingle my item with theirs.
Just 10 minutes ago I paid 10% more for a tool at home depot because I honestly wasnt sure if I would get a fake version on amazon and 10% was worth being relatively sure.
Fyi, Home Depot should price match to Amazon for "sold by Amazon" items, though online purchases are valid only for matching not their 'competitor price -10%' low price guarantee.
A lot of other stores will do the same with online competitors (or their own online pricing). My example from 2 days ago is Target price matching 2x2032 batteries from $7 to the target.com price of $3.
I read the article (I pay for WSJ) and there's one area they didn't mention: books.
I see a lot of books, especially business, productivity, time management books, written by authors who churn out poor quality (but legit, in that they're not filled with nonsense which is another scam) books by the dozens that mostly are the same book but freshened or rearranged. These books are low-cost so I've taken a chance on a few of them.
What made me try them if they have hundreds of legit looking reviews and 4 and 5 star ratings. I imagine there's some sort of "farm" for Amazon self-publishers that does this.
There are a number of services that will generate fluff reviews for your book. You take a risk, though, because if Amazon detects them, you're getting delisted. Also, Amazon will flag your book if your friends and family review it.
It really is mind blowing how spam has transisitioned from email to reviews on everything online. I wonder what laws apply in terms of having fraudulent reviews on something and it is considered advertising. I assume laws would have to be changed.
> The Amazon spokeswoman said it determined that fewer than 1% of hundreds of millions of reviews were fake last month...
Maybe they meant this to be a positive statement, but to me this just means they're not catching anything except the most egregious cases. Any cursory look at a popular product makes this look like a silly statement.
Why are they boosting rank for clicks? Of course that won't work. They know who actually bought the thing. Even that can be gamed, but it gets expensive to buy and ship stuff to yourself.
1 in out of every 5 items I buy from Amazon India has this small letter inside which goes something like "leave us a 5 star review and email me the screenshot to get 50 rs by paytm." And more often than not these products are filled with 5 star verified reviews.
The worst offender recently has been a fitness tracker called Goqii which is a completely useless gadget imo but has more than 22k positive reviews on amazon.
There have recently been some massive purges of reviews, including many real/organic reviews. I've heard from many sellers that they lost a ton of reviews on listings, even though they never made fake reviews or otherwise messed with it. It seems to be specific categories and some are saying it's concentrated in categories where Amazon has their own PL brands.
Technical question maybe someone can answer: Why doesn't Amazon just block all incoming connections from .bd, etc. ? If not block then depreciate the activities locations where this problem occurs frequently?
I have actually written a script in the past specifically to periodic collect and update all Bangladesh IP address blocks assigned from ARIN. They are the #1 source of spam on the web sites I work on. I had to go to these lengths due to getting non-stop calls all night from content teams needing help stopping them from destroying the web sites.
You think click farms in Bangladesh can't establish VPN endpoints in the USA? You can even get VPN endpoints that are specifically in Comcast, Verizon FiOS, charter, CenturyLink residential IP space so that it doesn't look like your traffic is coming from some /22 assigned to a Colo/dedicated server hosting company.
That means it wouldn't outright prevent the behavior, but it would add some cost and friction. That could reduce the sheer volume of the problem to make it worth it.
Maybe even not blocking them outright but just rate-limiting would provide comparable friction. It could even be more effective if they never try the VPN route to discover that it's faster.
You're overestimating the cost of bulk VPN services. It's like $1.50 per click worker desktop PC terminal per month, and that's if they don't have a decently skilled sysadmin to DIY it.
If you limit the IP to the residential IP space then VPN costs become huge. You need some resident to rent his IP to you. If those residents get punished by their providers for that behaviour then soon you will have to rent apartments to buy your own connections. That's hundreds of dollars.
Now, if Amazon would be sincere about preventing fraud, they would ban the IPs of fraudulent comments and somehow cooperate with the providers if they use random IPs. In other words, you would have to rent a new apartment for every bad review. That's an exhibitive cost.
I didn't make any specific cost estimate, merely stating "some". I'll grant that $1.50 is actually "none" iff it's a negligible fraction of that worker's monthly earnings.
With "wages low skilled" at 4650BDT [1] that's $55.50 at today's exchange rate. I'm standing by my estimate of "some", as a 2.7% "tax" on income isn't negligible, and could have far greater significance for those who earn at the bottom of the scale.
This needs more visibility. I've worked for Hola briefly, their business model is truly shameless. Hola is a free p2p VPN used as a browser extension, and they sell access to this network of users via the "luminati" brand.
I always get the impression Amazon doesn't care about customers until they complain, and then they are suddenly very nice.
Why not add some obvious QA features like:
- reporting fake reviews
- reporting fake/misleading listings
- reporting fake reviewers
- reporting listings where the product has been changed for something else
Many other glaringly obvious issues:
- vastly different products listed on the same page (to gather more reviews & sales = better ranking)
- shipping cost > item cost
- sellers promising a refund for a good review (especially to those that complain)
- fake 'only 1 left in stock' listings
- always-on-sale listings
- ...
Also while I'm complaining, as a frequent Amazon shopper there are a few missing filter/search options, in particular:
- listing age
- not deliverable to your address/country (frequent issue I have with cross-border shopping)
Weren't there sites where you could check if reviews and ranking are real or not? They used a pretty impressive algorithm. I wonder why amazon doesn't use something similar.

That said, I don't use their browser extensions so I'm not sure how they (if they) monetize that. I just paste in the URL to the product I suspect is 'too goo to be true' into the fakespot site. If it passes that, I do my own other digging on the item to determine if I think I can 'trust it'. Mainly, co-mingled inventory, seller ratings, cherry picked 1-star and 5 star reviews, other review websites, etc.
I've never had a fraudulent item purchased that I'm aware of. I hear this all the time on HN when Amazon comes up, yet haven't once experienced it and have been using Amazon for years.
If it did happen to me though, it would definitely sour my experience.
I've never bought a fraudulent item, either -- nor have I paid an exorbitant price -- but that's because I'm rigorous when I shop. What I said in my original post is that it takes more effort to shop now.
I don't know what to think about you and other "Amazon is all hunky dory" posters not seeing ripoff garbage all over -- because I see it literally everywhere. Do you not actually shop that much there? (Unlikely, otherwise you wouldn't have posted.) Are you easily duped? (Uncharitable and unlikely for HN demographic.) Do you buy only books?
I think I see what you're saying now. I have bought for so long from online retailers that it's kind of automatic for me to realize there's a lot of garbage listed in shops that allow third party sellers.
It was always par for the course to be extra careful before I buy, never had a lot of trust in online retail products.
Same here, but it's because I find it very easy to recognize the Chinese "brands", signs that a product is just Prime arbitrage, fake reviews, etc. If you want a selection of these lower-quality listings, take a look at lightning deals. I think actual counterfeits are fairly rare compared to just garbage knockoffs, but I also don't buy many products that are highly counterfeited.
I would say 50 percent or more of the items I buy from Amazon are counterfeit. I suspect clothes, almost all books and electronics are fake. Amazon tacitly accepts it to boost their sales figures.
I ordered these boxing wraps a year apart. The second time they were noticably thinner and worse quality. I suspect they were counterfeit but I suppose it's possibld that the manufacturerchanged how they were made. Either way that doesnt changed that i did a buy it again and got something different.
Amazon "won" in this case because for the cost it wasnt worth my time in returning them.
Is there a reason Amazon doesn't limit reviews to verified purchasers? I always assumed unverified purchase reviews were fake or else biased reviews in exchange for a free product.
> Is there a reason Amazon doesn't limit reviews to verified purchasers?
When the Amazon review system was created back in the 1990s, there was no requirement to purchase the item. That led to people often reviewing books they got from the library, or books that they already owned in their home library before Amazon existed. There were no scammers around to ruin things yet, and even if people weren’t buying every book from Amazon, they were still drawn to the site by these social features, the very vibrant "community" of book fans.
Over the past few years, Amazon has already removed various community discussion forums. Apparently, now that the site has reached a dominant market position, it feels that social features are no longer necessary to attract or retain customers. As part of these changes, Amazon has also reduced the visibility of non-verified purchase reviews on many listings. Still, its efforts are gradual, maybe it feels that completely limiting the review system to verified purchases would be too drastic a step.
I agree with you however it's much more than that because verified reviews can also be fake. There have been incidents of sellers creating bot accounts and buying products and shipping them to random addresses so that they can give themselves a verified review. The random person gets a free product (usually something very cheap, not the actual product). There was an interesting podcast about this. I generally look at the number of reviews, their distributions and the reviews posted by people with 1*.
Yeah and I have to wonder if company's are reaching out to purchasers who leave negative reviews and offering them incentives to "update" their negative product reviews. I came across a review from a person who bought a Jackery Bolt phone charger who claimed the company did this after she wrote a negative review on Amazon of their product.
Even big companies like Cherry behave fraudulent on Amazon, shipping different items under well known legacy product names. Amazon has a huge problem with its sellers. It is time for them to solve this.
As a collector of books on (among other topics) politics & religion, I've been thinking of buying a 73 volume full size Schottenstein Edition of the Talmud for quite a while. However, these usually go for > $2,000.00 in the US and > $3,000.00 in Europe. So you can consider my surprise when I stumbled on a new set at Amazon that's sold at $509, with only $14.95 shipping to Europe.
So I ordered the set. After some days, I get a notification that the set has been shipped. But no tracking number, which is odd for a shipment of such value.
After a week or two, I contacted the seller if they could give me a tracking number or at least confirm the address they sent it to. They gave no tracking number a confirmed the shipping address, but left out the country.
So I asked in response if they could confirm the country. I then was told that the address the shipment was sent to was the address in my contact info, without details.
So I again contacted them with the request to explicitly confirm the shipping country. Then I was told that they could not find me other and therefore refunded my money.
Then, I noticed several buyers complaining about items sent to the wrong address, packages being incomplete, etc :
* "1 out of 5 stars I ordered Love is in the Earth, a Kaleidoscope of Crystals. 7/30/18 -I received the wrong book in error Love is in the Earth- Laying on of Stones. I have contacted the store through Amazon, received a response and sent photos of the wrong book cover, back, spine and invoice. Awaiting response"
* "I have been back and forth with this seller about sending us two copies of the wrong ISBN. They have yet to provide a full refund for both books we ordered. They only provided a 50% refund at this point, and it has been more than a week of attempting to get our money back. Do not trust this seller to provide you with the correct items!"
* "Only one book out of the 10 book set arrived. A mistake was made. The seller responded timely and was very courteous."
* "The book arrived well before the expected delivery date but it was definitely not the version I ordered. The description was for the beautiful UK cover edition and I received the cheap mass market paperback production version. Contacted the seller and after multiple e-mails back and forth and pictures sent they ended up refunding the cost of the book so I ended up just paying for shipping."
* "The order that was listed as delivered on June 26, 2018 never arrived. The seller had us confirm our shipping address on July 7, 2018. Now it is July 26, 2018 and the missing order issue has not been resolved. Time for a complete refund of purchase price and shipping costs bookercafe."
* "I have not received my order and it is saying delivered. Can you tell me who signed for this? ORDER NUMBER 113-3032376-5177066"
* "I have purchased two books from this store and one of these orders had been canceled without notification and a fake tracking number has been submitted for the second one. Please refund as soon as possible."
* "lists books they actually don't have. now I have to be troubled to ensure I am refunded."
* "My book never arrived at my mailing address, even though there was a USPS tracking number. When I contacted USPS, they told me it was delivered to the shipping address listed on the packing slip (which was not mine). I contacted the seller, and they told me it must have been a bad tracking number. Haven't heard back...haven't received the book either. I have now submitted a refund request."
* "1 out of 5 stars Another reviewer called it a scam when the book didn't arrive even though there was a tracking number that said it did. Seller told him it was sent to another address. Guess what? Same thing happened to me. A bad tracking number and the excuse that it was sent to a different address. I never heard from them again after they said they would check into it. I've submitted a refund request."
* "I ordered five books from them. One arrived OK, the other four never came but they kept my money for almost a month. One had no tracking number, the other three all had fake tracking numbers, re-used numbers that showed the books were delivered to three other cities. I had to fight them and contact Amazon to get a promise of refunds, and they are still stalling. Cheaters"
* ...
Overall, however, customers appear satisfied and the store has a feedback score of 91% for 335 ratings.
However, judging by the fact that 309 of those reviews were from the last 90 days, the store seems to exist only about 4 to 6 months on Amazon.
Something else I noticed, is that I get their > 400,000 results and that there are quite a few items listed for the same amount of $509, most of which I can't imagine are actually worth that much and are sold by other sellers at much lower prices :
The item I ordered has been re-listed at the same price point, a bit after I received my refund for it.
Interestingly, there are now 6 sellers offering the same set with "Used - Good" condition and prices ranging from $506.00 to $548.32. There were only 3 sellers when I checked last time. All of these 6 sellers have a storefront with 300,000 - 700,000 items in them. And this includes a new shop that hasn't sold anything yet!
Since I received my refund As the store I ordered from is the only one shipping to Europe, I asked them if they'd ship be willing to sell it to me again. First they were eager and even offered a 30% discount. When I asked if they could add tracking for a second order, the tone became less friendly and I was asked to remove my (negative) feedback for the initial order.
I'd also asked an explanation for what went wrong with my order but haven't received any.
I also came to notice that this seller uses a kind of broken English very reminiscent of the broken English of sellers on AliExpress. So I suspect that her native language is Chinese and this account is a good example of a Chinese scammer account. And the same probably applies as well to the other 5 accounts I spotted which sell the same item at roughly the same place.
AliExpress sure has its flaws, but I never really had that much issues with ordering on AliExpress. And I certainly never came close to experiences as strange / fishy on AliExpress as my recent experience with third party sellers on Amazon... which really surprises me, as this type of seller should be easy to spot, even by an algorithm!
I'll definitely think twice next time I see an interesting book - or set of books - on Amazon that's sold by a third party seller! I feel like Amazon urgently has some serious closet cleaning to do!
My strategy has always been to read the 1-star and 2-star reviews, most recent first, unless there are so few total (e.g. under a dozen) that I may as well just read them all.
Positive reviews, even 4-star and (enough of the) 3-star tend to be useless to me. What I want to know is why people hated the product. If it's exclusively for reasons that don't apply to me or for risks/problems inherent to the type of product, then I have what I need.
Negative reviews are often also where the best referals to alternative products can be. Of course, those have a high enough likelihood of being posted by a shill that one can't assume it's actually better without reading those reviews, too, but it can beat grinding through all of Amazon's search results.
All that said, the worsening counterfeit and delivery situation means I've bought hardly anything in the past year, after a progressive decline in buying the year before.
