I've been using theLog In app for about five months, I think, and I'm just about to cash out for $5. Now, I know that's not much, but I didn't have to work very hard to get it either, plus it's kind of fun. All you do is take a quick picture of your receipt with the app and upload it. This takes me about a minute, and I do it right before I leave the grocery store so I don't forget. The app also has a slot machine that you may use to get free credits towards your reward. Rewards are issued either as cash or a gift card for Amazon. Easy-peasy. Yeah, it doesn't pay much, but $5 for little effort on my part is kind of nice.
