Most of the items found on this rebate are items that you would buy on a weekly basis, such as milk, yogurt, eggs, garbage bags, cereal, soda and more. This app ranks high due to the high rebate amount (sometimes as much as $5 for one product) and is constantly growing with new product rebates coming out every week. Ibotta was one of the very first rebate apps available for grocery shopping. Ibotta takes the #1 spot due to its variety in choices and its long-ranking history.
