If you are a WalMart shopper for anything, download the basic app and it has "Savings Catcher". All you have to do is scan the very bottom of your receipt with your phone and the app searches the area stores for better deals on the items you've purchased. If it finds a better price, it will refund it to you! I have already cashed in over $50! No more searching through the ads, no more remembering to take them with you. My app says it searches 27 area stores.
