You can't assume they will do that everywhere. I was in CVS, and it seems like rather than discounts for "loyalty" they have jacked up their prices if you don't have the card. They said they would look me up by my phone number, but when they didn't find me, that was it, no discount. I said fine and left the overpriced batteries behind.

I don't know why grocery stores don't seem to care, whether it's corporate policy, or employee culture.

I don't. Personally, I don't care if they do this or not -- it's entirely irrelevant to me. I was just noting it out of amusement.

In general, I tend to avoid stores that have a loyalty program, because (as you note) their "loyalty card" prices tend to be the same as the normal prices at stores that don't.
