Good idea, but...

I like the idea of earning extra money from your receipts, which the app likes to remind you that "you would have otherwise thrown out"... But unless you shop for groceries every day and pick up other peoples receipts in the parking lot (which youre not supposed to do), itll take quite a while to earn anything (especially with lopsided reward levels per receipt- a $48 receipt gives you the same number of coins as a $12 receipt, even though you spent four times as much).This app is more trouble than its worth.
Edit 1/18/17- Docked an extra star because I can do math and realize that the new change to the cash-out levels does not benefit the user- luckily, I just reached 1000 coins, so Im cashing out and deleting.
