The Cartwheel app: Everyone knows that spending money at Target is a little too easy to do. That's why you're seriously missing out if you haven't tried the Cartwheel by Target app yet. Not only can you search the app for existing coupon deals, but you can also scan the bar code of any product directly within the app to see if it has a discount. Target brands like Archer Farms and Up&Up usually do. Have your cashier scan your app at checkout after you add deals to your cart, and you'll save money on food little by little.
