Fun fact but Central Market actually operates on the same margins as HEB. Their produce in particular is competitively priced. Where they get you however, is that all of their produce is jumbo sized. So yea, you have a competitive price on the apples per pound, but if you want 6 apples, they are on average going to be more than from HEB or a different supermarket.
Subtle, but it allows them to make some fun marketing claims!
