If an online store has a money back guarantee when prices fall or a price match guarantee, Paribus makes sure you never miss out of any potential savings. With more than half a million members, the free app has the potential to save you hundreds each year.

How it works

Paribus monitors prices from many of the largest online shops, including Amazon, Apple, Gap, Banana Republic, Old Navy, Walmart, Costco, Target, Macy?s, Bloomingdales, Nordstrom, Staples, Office Depot, and many others. Prices on everything every type of product are tracked so you get cash back whenever you shop online. The app tracks receipts sent to your email and identifies any coupons or price-match guarantees. You simply sign-in with the email you use when you shop online and connect your account with shopping outlets. When you get a refund, Paribus charges 25% of what you save with no additional fees.

The bottom line

If an item you buy goes on sale soon after you buy it, you could potentially save money if the retailer has a price drop or match guarantee. To do its job, Paribus needs secure access to your email so it can track receipts. Webhooks are used to detect receipts based only on the sender and subject fields. Although information is transmitted over SSL and bank-level encryption is used to store data, this might cause concern for users that worry about how their data is used.
