Paribus

Paribus is an online price tracker that allows users to make the online purchases without worrying about comparison shopping or price drops. Paribus automates the process of following up on past purchases to see if shoppers can request a refund from the online retailer, helping online shoppers get automatic refunds when prices drop on items they purchased. Paribus integrates with the user's email provider and scans their inbox for receipts of online purchases, and then watches the item for a price drop within the store's price match claim window. The service works with a number of online retailers. Stores change their prices all the time. Get money back on price drops you didn't even know about!
