All I can say is, "wow!" This article at Webware talks about a great website that will help you save money the next time you want to take a trip. The website it called Farecast and provides powerful tools for searching a range of dates, times and airlines in order to find the cheapest acceptable fares.
You can also set a price between two places and it will tell you when the price gets that low. It will also tell you how the price of the ticket will be affected if you change the range of dates by shortening or lengthening your stay. I know I'll be using Farecast in the future!
