Any store where you need a club card to get the sale price. I refuse to shop there. Don't act like you're giving great customer service by giving me the sale price. It's CVS, not an industry discount at fashion week. We all know it's marketing/consumer tracking. Meanwhile, the person ahead of me is reversing the customer service because they're slowing down the line because they forgot which phone number they need for the register to charge them the sale price.
