But my gf just told me about the "Checkout51" app
There's different deals every week, (for example, $2 rebate on Cracker Barrel cheese)
You simply take a picture of the receipt and send it through the app
Once your rebates hit $20, they send you a cheque.
It adds up fast, and if you think about it... this gives you a better return than most cash-back credit cards!
I lol to myself when a loaf of bread is $2, and the app gives me a rebate of $1.50

There was also a time when a carton of Minute Maid OJ was on sale for $1, and the app gave me $1.50 rebate, so it's like I made 50 cents and got free juice. lol
