Yapta: Protection from Overpaying for Airfares

Did you overpay for your last airfare? Most of us can't really answer the question because once we pay for the tickets, we stop shopping. But a relatively new service called Yapta keeps checking the prices on a specific flight and notifies you if there is a change. Yapta also tracks individual flight fares before you buy. Find out more about how Yapta works and whether or not it should be added to your budget travel toolbox.
