I just got an email earlier today from TripIt, the company behind the website (with the same name) that lets you automatically put together travel itineraries from your confirmation emails. This email gave me a link that I can give out to friends so they get $5 off for the yearly subscription fee for the pro version otherwise priced at $50 (which you get for $44).
Note, I do not earn a kickback from this, I just wanted to share it with you since I use the service and love it deeply and hey, any way that you can save a little money right?
