This is not a new site, but it is new to me. I thought others might like it too.
Pruvo is a free online web-service that tracks price drops to existing hotel reservations and notifies you when it finds a better price for the exact same hotel room you booked. The service is free and the only requirement is that the hotel reservation be a free cancellation reservation.
