EBates

Similar to Ibotta, Ebates awards you with up to 40 percent cash back on items you would normally buy. There are more than 2,500 participating stores — including Walmart, Amazon, Groupon, and Expedia — and you can set the app to notify you when there are new coupons available. If you choose a specific item you want to purchase, Ebates will also show you which stores are selling said item and how much cash back you would receive from each store. Moreover, Ebates is currently offering a $10 bonus when you make your first purchase.
