Cash back for buying groceries

Another App I use in checkout 51. This app lets you choose offers and shows you how much cash back you will get. You then take a picture of your entire receipt and upload it to the app. Within a few days you get an approval and the cash back goes into your accounts. The only catch is they will not issue you a check until you reach $20.00. 

So far I have $3.00, honestly sometimes I just forget to upload my receipt..I would probably have more money if I did.
