Editor’s Note: After a change in Amazon’s Price Guarantee policy, Paribus has retooled its business model. Paribus now helps its users get refunded for price changes through its select credit card’s price protection plans. See their website for full details, and to see if you have a qualifying card!

I’m a notorious email saver.

I rarely delete anything — especially not receipts.

Turns out that was a smart policy. In the past few months, it’s earned me $22. And all I did was shop online like I normally do.


Wondering how saving your emails could earn you money?

Then keep reading…

How I Earned $22 Without Doing a Thing

My new secret weapon is called Paribus — a tool that gets you money back for your online purchases.

I’ll use an example to illustrate how it works…

Let’s say you purchase a toaster at Amazon for $20. The next week, Amazon drops the price to $15.

Like many retailers, Amazon offers a price guarantee for the first week or two after your purchase, so you’re entitled to a refund for the difference.

The only problem?

None of us have time to check and see if prices have dropped on our purchases.

That’s where Paribus comes in.

It scans your email for receipts. If it discovers you’ve purchased something from one of its 18 participating retailers, it tracks the item’s price.

If Paribus notices the price went down on the toaster you bought, it alerts you and contacts Amazon on your behalf.

To uphold its price guarantee, Amazon refunds the $5 difference to your original method of payment — so you’ve earned money without lifting a finger.

For its role in the refund, Paribus charges a 25% commission, billed to your credit card at the end of each month.

In this case, its commission would be $1.

Your first claim, though, is always commission-free.

You can also lessen Paribus’ commission by referring others. If five of your friends sign up, your commission charge is zero.

Is Paribus for You?

Since I do most of my shopping online — and the majority of it on Amazon, where prices fluctuate millions of times a day — I’ve been super happy with Paribus so far.

The only downside is you have to give it access to your email and credit card, so it can automatically find receipts and pay itself commission.

That doesn’t bother me, though.

Paribus has advanced security: It “employs multi-level security mechanisms including dedicated firewalls, VPN services, intrusion prevention systems and stringent access controls,” and it transmits data using bank-grade encryption.

If it didn’t, no one would use it — and it probably wouldn’t have acquired 200,000 users. Honestly, the fact it’s so automated is my favorite thing about it.

For me, giving Paribus access is worth it and one of the easiest ways I’ve found to save money without doing a thing!

Your Turn: Would you like to give Paribus a try?
