12. Find out if retailers owe you a refund
What’s worse than paying for an item only to find out later that it went on sale? You might think you’re out of luck and that you should pay more attention to upcoming sales, but Paribus has got you covered.
If you open a free account with them they’ll look through your inbox and check receipts. Then, if they find a price drop they’ll help you get the difference back. This also works with Walmart and Amazon purchases.
The cherry on top is that they’ll even aid you with items that are shipped late, as they’ll make sure you’ll get your money back. It’s a great monitoring tool that you should take advantage of if you’ve ever felt swindled by online retailers.
