JUNE2017P12B10 "You do not have permission to use this coupon". Well? It isn't purported to be Prime Member only, so? Why don't I have permission to use this coupon. Just as I was getting the impression that Render Rewards might be useful, Prime or not I get this sort of nonsense. I just want to give you money for stuff when you clearly offer a coupon and have items that are labeled as accepting of coupons in my cart. Yet you keep finding ways, apparently, to dissuade me from spending my money here. Don't you like money?
