IBotta offers cash rewards for purchasing your favorite products. Common grocery items, like Pepperidge Farm cookies and Coca Cola products, appear in the app with a cash amount listed. To earn the reward, you have to select the items you want to buy and complete the mini-tasks required -- usually involving nothing more than reading a short blurb or answering a survey question -- then select the store where you plan to make your purchase. Once you’ve bought the items, snap a photo of your receipt and upload it to iBotta to receive credit for your purchases.
