I don't believe this is fair. I walk into the supermarket and consciously attempt not to eat the first crap I come across, and it costs me vastly more than if I just went and bought a 10KB tub of mayo and ate it with a soup ladle.
Not only more money, but more time, and potentially more distance (which can be described in terms of time and/or money).
For example, Whole Foods bought and closed a Wild Oats store in the same shopping complex as a Walmart. Less than a year after closure, that Walmart no longer carries organic produce. The closest store with an organic produce selection is 4 miles away.
Whether or not you think organic food is better or worse is irrelevant - Walmart offered a product to compete with another store, and once that competition was gone, they dropped that selection from their store.
