B&H, an electronics super store in Manhattan, is owned by Hasidic Jews, and it sells new and used gear. The web site won't even take orders on Shabbat. I wouldn't be surprised if some of the people selling new or used electronics have some connection to B&H or another brick and mortar store.

B&H has been our goto place for electronics / computers lately. They deal well with educational institutions, will take a PO from an community college on a reservation in North Dakota, and have excellent customer service.

I do keep track when I can order, for instance right now they are closed for Succos.

I had no idea. Ordered some camera gear from them years ago and they had great prices/service. Cool.

It's not so much an advantage as a drawback; big families led by people with no formal (in the what society expects sense; Talmudic study is quite formal) education and strict gender roles. They also have to drop everything and pray three times per day so I don't know how well that jives with "normal" career.

What I got out of it is they spend a lot of time doing intensive Talmud studies, and perhaps that teaches discipline and hones intellectual skills.

Then someone with this background finds themselves struggling to support their family and they realize that with some hustle, they can do it through Amazon.

I believe the only advantage is being near a large city so there's a lot of stuff available to buy at a discount. NYC is a very interesting city. The other possible advantage is that self-starting is an admirable trait amongst the Hasidim.

1) I doubt the NYC merchandise itself is the advantage, rather it is the concentration of Hasidic entrepreneurs which provides invaluable networks.

2) The need to support a growing family from a young age with no formal education, propels many to try their hand at business.

Yeah, a lot of people locked out of traditional careers turn to running small businesses. I'm sure it helps though if everyone around you tends to run small businesses as well -- cultural expectations probably push you towards it, and you have a wide support network.

I know nothing about the culture, but if the fathers are already in these trades and instill a business mindset in their sons early on, it makes sense that they excel in running the trades they grew up watching, listening, studying, and helping their fathers run.

There are also some online communities that facilitate networking in this area such as https://forums.dansdeals.com/

IIRC there is even a Hasidic version of Shark Tank floating around on YouTube
