If you’re going to subscribe to Hulu, read this.

You might as well be throwing money away if you’re not using . This Chrome extension knows nearly every trick in the frugal bible and will automatically try them for you (and the 3,000,000+ other people currently using it).

Here’s how it works:

Shop at Hulu, Nike, GameStop, Sephora, Forever 21 or almost anywhere else? When you make a purchase, you’ll automatically earn shopping credits. Then, you can redeem those credits for gift cards later on. Yep, it’s like getting paid to shop your favorite brands.

Ever shop on Amazon? automatically checks other sellers for a better price, including sales tax + shipping. A notification will appear in seconds if a better offer is found.

The best part? It’s completely free. Do yourself (and your wallet) a favor and get Capital One Shopping .
