Paribus is a great app that tracks your purchases via receipts in your email. If the price on the item you bought drops, you get a REFUND!
"Paribus scans your inbox for receipts and automatically saves you money when the items you bought drop in price. Stores often guarantee that you will get the lowest prices. They even promise to price match. But they don’t follow through unless you work for it. Paribus does the work for you. When you are owed money, Paribus automatically gets it for you. Sign-up with your mailbox and Paribus handles everything else: Automatically detect purchases, monitor and compare price changes in real time, and engage with stores on your behalf to get you paid."
Paribus does charge you 15% of your refund as a success fee, but if you invite three friends, that fee drops to 0%!
