6. Snap by Groupon

Groupon, the already successful money saving website has provided us with another way to save even more money. Snap by Groupon offers it’s users reimbursements when shopping for groceries. In a similar way to other apps in this list, you have to do your shopping as normal and photograph your receipt. When you have made a minimum of $20 you can then start to cash out into your bank account.
Oh I almost forgot, you also get $1 each time you refer someone to the app! Smart move.
