Think travel has to be expensive? Not anymore.

Karma is a free shopping tool that helps you find lower prices on flights, hotels, car rentals, attractions, and other travel essentials. From comparing prices to applying coupon codes, this extension knows almost every money-saving trick out there.

Here’s how it works:

When you book flights on sites like Tripadvisor, Expedia, Hotels.com, Booking.com, Vrbo, Priceline, Orbitz, Trip.com, and many more, Karma quietly searches in the background for the best coupon codes to apply at checkout.

For example, these plane tickets to Hawaii were discounted by $214, without losing your carry-on or having to choose a “budget” airline. Same American Airlines tickets, just a lower price.

Karma even works outside of travel. It compares prices on Amazon, so whether you’re shopping for luggage or a beach outfit, you can get it for less.

Last year, Karma saved its users over $330 million. You can install it in seconds and easily uninstall if you don’t like it, so there’s no reason not to try it now.

The best part? It’s completely free. Get Karma HERE.
