Amazon Price Helpers

Amazon will refund you the price difference 30 days after you buy an item.  These sites will monitor the price and email you if the price drops lower than you bought it for.

Flamingo World’s price watcher has a nice interface which lets you preview the item after you enter the item number

RefundPlease is another Amazon price watcher.  The site claims to be working on compatibility with other sites, so keep your eye on this.

Webgadgets will show you a graph history of the prices on Amazon, as well as listing entire Amazon wishlists.  Price histories are better for more popular items since the prices seem to be tracked whenever someone views the graph for the item.  Also offers rss feeds for item prices.
