But we do not sell the cards at all. I really don’t know how else to reply to the reviewer. It feels biased now. Shopkick earns points when the User enters a grocery store and checks in, when he scans his or her receipt, and when he answers questions. Same with Swagbucks and InboxDollars. All of these require some form of concentrated effort on the part of the User. Mine simply allows you to collect Diamonds, similar to a grocery store “check in” in a way.
