Don't throw those receipts away! The following apps will give you cash back just for sending the pictures of your receipts.
Walmart savings catcher will look at what you have bought and if any other store has the same product listed for cheaper, than Walmart will pay you the difference in the form of a Walmart gift card. You can submit 7 receipts a week. Don't just stop the savings with your own receipts. You can benefit from other's grocery list too! On one shopping trip a couple of weeks ago, I happened to find a couple of long receipts in the parking lot on the way to my car and got almost $10 cash back from scanning them into my Savings Catcher app!
Ibotta has a huge list of products that you can earn cash back for buying. My favorite thing about ibotta is that a lot of the products on the list are things that most people buy every week and they don't even have to be a specific brand, such as yogurt, milk, eggs, and bread.
Bonus: When you sign up they will ask you if you have a referral code. If you enter mvmrryf you will get a $10 bonus when you redeem your first rebate and I will get a $5 bonus.
Receiptpal rewards you for any receipt you take a picture of from the past 30 days. It doesn't just have to be for groceries, it can also be for restaurants, toy or clothing stores. Pretty much anything you would get a receipt for. You get rewarded in the form of various gift cards like Restaurants.com, BestBuy, Lowes, Home Depo, Target, and Walmart.
Receipt Hog will give you points for every receipt you snap a picture of, regardless of what you bought or what store you shopped at. They pay in virtual coins that you can redeem for Amazon or PayPal cash. They even have a fun little slot game that you can play as a bonus for snapping receipts. You can win some pretty nice prizes like $100, 400 coins, and you an even get redeemed for the price of your last shopping trip.
Shopkick: This app is a little different than the others. You get awarded "kicks" for different things such as checking in on your app when you walk into the stores on the list. You also get paid for scanning products when your in the store. Some stores such as Old Navy and JC Penney will even award you a kick for every dollar you spend there. You can redeem your kicks for an assortment of gift cards.
Here are the additional honorable mention grocery apps that I use. They don't always have a product that is on my list but there is a good chance that they'll have at least one or two staples. It’s always worth giving them a look before you toss your receipt. You don't want to leave any rebates unclaimed.

Update: I wanted to add a couple of apps to the list that I recently discovered.
Checkpoints: This app is similar to Shopkick in that it pays you to check into stores and scan items. You can also earn 500 points a day just for letting videos continuously play on your phone. I like to start the videos before I go to bed and then by the time I wake up I have a ton of points added to my account. You can use my bonus code heathermgc68 when you sign up!
Find and Share: This is a great app that gives you a percentage cash back from different stores and restaurants you stop at. They have tons of stores and restaurants to choose from. I even got cash back from shopping at the Dollar Tree! All you have to do is take a picture of your receipt. Bonus code when you sign up- HGXC.
Kellogg's Family Rewards: If you buy any Kellogg's products then just take a picture of your receipt to get rewarded. You can Download the app or use the Kellogg's Family Rewards website. You can redeem your points for gift cards or cool products like camping gear and kitchen appliances.
