ReceiptHog is an app that you can submit your receipts to earn points that can be redeemed for Amazon gift cards or cash via PayPal. It takes awhile to earn enough points to cash out, but it doesn't take much effort and certainly gives a good boost to the grocery budget when you are able to redeem for $30 (about every four to six months for us).
You used to only be able to submit grocery receipts, but you can now submit pretty much any kind of receipt. However, not all receipts earn you coins. Mainly places where you buy groceries such as supermarkets, convenience stores, pet stores, dollar stores, etc. are ones that earn you coins. The amount of coins you earn varies based on how much you spend (max 20 receipts or 275 points a week). Other stores like for clothing can be submitted to earn you spins. All receipts also give you an entry in the monthly sweepstakes.
Spins are earned from certain receipts that don't qualify for coins. They are also earned when you submit at least one receipt a week for a certain amount of weeks each month. If you're lucky you can win a lot of coins from the spins, but I find I rarely win and when I do I get like 2 coins, so really the spins contribute very little to being reaching 4500 to redeem for $30.
Overall I find ReceiptHog a useful app for not only having records of purchases, but earning some extra money for groceries. It does have options lower than $30 to cash out, but you get way more for your coins if you wait until you can redeem for $30. For example, $5 costs 1,000 coins, but instead of costing 6,000 for $30, it only costs 4,500. Also, it's the same value whether you choose to get Amazon or Paypal. I always go with Paypal because then I can use it wherever we want to get groceries including buying an Amazon card on
