Thanks to RSSTalker.com you can track products on Amazon.com and be alerted via RSS when the price changes. This would be awesome if you had a product you wanted (like an MP3 player) but you wanted to wait till the price came down just a little ‘bit.

RSStalker.com provides XML based RSS feeds to track price changes of Amazon.com products. Generate a feed for a single product or for an entire wish list. Add it to your favorite aggregator and you will be automatically notified when the price changes. Simply unsubscribe to the feed when you are done.

I have plugged in a few “tests” to see how well this works, and I have to say I am happy with what I see. You can also: make an RSS feed from your wish list at Amazon and create an Amazon category RSS feed.
