PriceAlert for Amazon is a simplified menu bar tool that allows you to monitor the items you would like to buy from Amazon.com and notifies you once it reaches the price you set.
ShadowBid is the best way to save money on Amazon! Prices change up to 80 million times every day (shocking!), and we help you take advantage of all that volatility through automated purchasing when the price drops to the level you set. Find your product, view the price history chart, and set your price. We'll take care of the rest for you!
TrackChanges will compare what has changed since the page has loaded, then generate a set of developer friendly files.
