No, I don't want to save 10%
I don't want your store credit card. If I did, I would have signed up. Why do you want to harrass your best customers, those who are BUYING SOMETHING RIGHT NOW by begging them to get your credit card? I know they are big money makers, but it is not worth infuriating your customers. The next time you get asked this at a store, go to the manager and complain.
