Have you checked out Checkout 51 yet?  I just found out about it, so I haven’t been able to try it yet!  It looks fairly straight-forward and easy to use.

Checkout 51 will help you save money!

How Checkout 51 works:

1. Browse the offers and buy products at any store.
2. Upload your receipt using Checkout 51.
3. Your purchase will be confirmed and your account will be credited.
4. When your account reaches $20, you can cash out and receive a check.

Guidelines:

1. New offers are available on Thursdays at 12:00 AM in each time zone and expire the following Wednesday at 11:59 PM. Your receipts must be uploaded while the offers are still live.
2. Offers are available in limited quantities. Be sure to double-check your offer list before shopping to check to see if the offer is still available.  Upload the receipt immediately after purchase to avoid disappointment.
3. One of each offer is eligible for cash back per member.
4. You may only use each receipt once.
5. Cash back can only be given for the exact product listed.  Be sure to read the offer carefully.
6. You may use Checkout 51 cash back offers with other coupons or discounts (unless otherwise specified).
7. Products must be purchased in your country of registration. Currently the United States (excluding Puerto Rico) and Canada (excluding Quebec) are supported.
8. Receipts submitted must be in English.
9. Items purchased from online retailers are eligible for cash back. Packing slips are accepted as proof of purchase. Online purchases are subject to the same submission timelines as receipts.

If you use Checkout 51 (or have already used it), let me know what you think!  You can also compare it with the iBotta app (it is a pretty similar idea).
