Track the price history of items on Amazon.com, Amazon.ca, Amazon.co.uk, Amazon.de, and Amazon.fr. It is an extension of the Wish List Price Tracker for Amazon website. Your feedback is welcome, but I am at the mercy of my real job for time to work on new things.


Not all items are being tracked. If you add something and it doesn't have any history, it will start collecting a price history right away.


The image above shows a typical graph. The vertical lines represent weeks. The right edge is now, and the left edge is 90 days ago. The red and green horizontal lines represent that highest and lowest observed values, respectively.


You will get notifications of price changes for anything you're watching. I look for price changes every hour. If something that hour changes availability, whether or not the price can be displayed, or if the price drops 5% or more, you will receive a notification for all the items that changed since your last notification.


If you have any more suggestions for features, please speak up. If something is not working, please let me know. It is probably an issue with Facebook, but I would like to know in any case. Thanks.
