I usually use this mobile app for shopping at my local grocery stores such as Giant and Aldi. Frankly, I love the app and use it every time I shop to get some extra cash using the rebate. The app can be used at Walmart as well. I estimate for as little shopping that I do that I will get back about $300 of cash from this one mobile app in one year! If you want this app, just download it from the Apple App Store, or your preferred mobile phone.
