So im not sure about android phones , but there's an ap for the iphone ( maybe this is old news) . Its called key ring (rewards?) . You can scan all your key ring cards and have them put on your phone and just have the cashier scan the card on the phone. Also they give out coupons/rewards/offers as well . If you have no loyalty cards to put on you can join programs . For example, today i joined ci ci's pizza buffet program and it game me a coupon for free buffet dinner !! Also if you add your kroger card on there you can clip the digital coupons directly from this ap. Im sure there's many more benefits but im just discovering them one by one. lol Any input/experiences anyone has?
