Fighting amongst ourselves when we should be shaming the mayonnaise and baloney sandwich over-pricers. That’s the problem with the petite bourgeois and proletariat.

Shaming is so effective, the sellers' faces will turn red with shame, and they will immediately drop prices by 2/3 at least. Hah, hah, no, they won't. Of course, they will overprice when you have no other options.
