If you are shopping on-line and looking/waiting for the price of something to drop, you can use Price!pinx to do this automatically. IT's a pretty cool plug-in for your browser that, sadly, only works in IE. You can go to any site you want, you then highlight the price on the page and press the !pinx button on the plug-in and it takes care of the rest. It then monitors the price on the page and when the price drops. This is a cool service that works on any site where you can but things and it's free.
