Download the wholefoods app on your phone then open it and scan the barcode at the check out. The app will also tell you what's on sale and what you get extra discounts on with your amazon prime membership.
From what I understand, Amazon will be releasing coupons to their prime customers, which they will then be able to print out and take to the store. I'm not sure if that's the only thing they will be doing.
I suggest that you tell her. I don't have AP, so I haven't had the problem.
