I use RSS feeds for a lot of things -- watching articles on Google News for keywords, getting weather updates, and even, sometimes, tracking packages. I have not, up to this point, used RSS to track price changes. But now I have a tool to do that too!
RSStalker, at http://www.rsstalker.com/ , allows you track price changes for specific items on Amazon or for categories as a whole.
The site is very easy to use. Say I'm interested in DDR Supernova 2, a video game, but I don't want to pay $39.99 for it. At RSStalker.com I enter the ASIN of game ( B000UZVL9Y ) and RSStalker pulls up that item and shows it to me (so I know I've got the right item) and gives me an RSS feed address to subscribe to. Now I'll get an alert in my RSS feed reader when the price drops, so if the game ever becomes one of those PS2 classics that costs $19.99, I can pick it up then.
Maybe you don't want to watch one item at a time for price drops -- heck, maybe you're looking for bargains as the holidays are coming up. In that case check out the category feeds at the front of RSStalker. The video game feed, for example, tells me that Elder Scrolls IV: Shivering Isles, Tetris Evolution, and Brain Age 2 are three of the games that have dropped prices lately (note the RSS feeds also show when prices have gone UP, though that's a rarer occurrence.)
Hard to believe it's almost time for holiday shopping...
