Discount Travel Tools

I read about these in an article today:

AirfareWatchdog.com: Searches for the least expensive airfare for U.S. and International flights. See more here.

And Yapta.com: Tracks prices and refunds for airfare and hotels, and notifies you of lowest rates.

I find it is helpful to use more than one discount search site when booking flights and hotels. These look promising.
