Travel Technology - Software or webpage to track my itinerary price everyday

Folks,
I am looking for a web page or software that helps me track the price of a future itinerary and send me an email if it falls below a certain price that i specify for that itinerary or even buys it for me at that price i specify for an itinerary. I dont want to login and check everyday the price for my itinerary...is that too much to ask for?

THanks,

Please follow this thread in the Travel Technology Forum.
Thanks..
