Even those store loyalty cards are conditioning us to accept the idea that certain people get, or even deserve to get, different prices because of who or what they are. Prices should be transparent and it shouldn't matter how much money you have, or who you know, or how "loyal" you are (what a sick concept!) to a grocery store.
