The most satisfying way to save money?
When you don’t even have to try.
Pruvo is a service that saves you money on hotels you’ve already booked. You simply forward your hotel confirmation to Pruvo via email, and they’ll hit you back if/when they find the exact room you booked at a lower price. Then, you just rebook through the site at the cheaper rate and cancel your old order (note: Make sure your hotel has a free cancellation policy).
No credit card info and no signup needed. As well, Pruvo has a Chrome app tracks your hotel bookings and claims to find “hidden deals.” You can also just book rooms directly through the site if you wish.
