Earny
Earny gets you money back on almost every purchase you make. Stores promise that if the price of an item you purchased goes on sale within 14 days of your purchase, they will refund you the difference. Major credit card issuers guarantee the same policy for up to 90 days. Earny is here to make sure that happens. Once you download the app and register, Earny will take care of everything in order to get you money back. This happens without you having to lift a finger. Earny is not free but it also doesn’t cost you money. Earny takes 25% of the refunds he gets you, so basically he gets paid when you get paid.
