If you want to buy Whole Foods gift cards (which is why I got it) it flags it for fraud and doesnt let you. I was told you can spend at Whole Foods but not buy WF gift cards, even though it is a Prime Credit Card. Also if you buy WF gift cards online, you dont get the rewards since its from a gift card company and not Whole Foods.
