Well, no, that's actually not correct. You pay the same price as if you were paying cash and get the benefit of the 2% for using the credit card. The poster above posted incorrect information and subsequently corrected it. We do the bulk of our shopping at Costco. With meds, groceries, wine, household items and all the other stuff we spend 75,000 to 100,000 a year at Costco so the card is of real benefit to us without even considering the fact that we no longer have to carry wads of cash around.
