Karma is a free tool that helps you save on hotel rooms, flights, rental cars, and more — right from your phone. From comparing prices to applying coupon codes, this extension knows almost every money-saving trick out there.
When you book a hotel room 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 – even when you’re browsing on Safari on your iPhone.
For example, this hotel room in San Francisco was discounted by $54 — same room, same amenities, just a better deal.
Karma doesn’t just stop at travel. It also checks Amazon and other sites to make sure you’re getting the best price — whether it’s for luggage, travel accessories, or anything else.
The best part? It’s completely free. Get Karma HERE.
