Trip Stalker - Find Low Airline Fares

Finding low fare airline trips is one part science, and one part voodoo. Trip Stalker is a utility you can install that will try to make the process easier. The software takes your criteria for a trip, then silently checks various internet travel sites for the lowest fares for the trip you specify, and alerts you when it finds one that falls into the criteria you set.
