Checkout 51
An app that gives you cash back on groceries and gas.
What Checkout 51 does
Checkout 51 is a free US cash back app built around weekly offers. You add grocery offers or gas deals in the app, buy at any store or a participating station, then upload a photo of your receipt. Cash back builds up, and you can cash out once you reach $20.
Checkout 51 posts a fresh set of grocery offers every Thursday, mostly on everyday brands. Add the ones you want to your list, buy the items at whatever store you like, and upload your receipt to claim the cash back. You can also earn by taking surveys and by shopping online through the app.
Gas is the other big piece. You can find participating stations on a map, compare prices, and claim cash back per gallon. The rules are strict, though: once you add a gas offer you have four hours to fill up, you have to pay by card, and the receipt has to go in within 24 hours.
Your balance can be cashed out once it hits $20. That's clear and simple, but it can take a while to get there if you only use a few offers a week. The app also uses your location in the background to show nearby offers, and it warns this can drain your battery, so you may want to switch it off.
