It just doesn't seem to be worth the hassle. Most if not all my receipts are email..Amazon and Walmart because I do Walmart pay. But it always just checks my Amazon receipts. I keep trying to figure it out but not so far. Oh n also when they say to do this you'll get 2000 coins well I didn't. So I'm going to delete this but others say it's great so doesn't hurt to try it out yourself if interested
