Make your own Amazon Price Tracker

With google docs, article goes on how to use docs to track and alert you to a price point for a given amazon item.  You can do this thru other sites, but you have to create an account with them.  Me, if there is something I know I plan to buy at some point, I do set trackers to see if it goes down a bit before I need it.
