If you like to bag a bargain then this new Chrome extension released by Tracktor might be a useful tool for you to use when shopping.
Simply install the Chrome extension and Tracktor will show you the price history of any products in Amazon.
You can review the three month, six month, one year, and lifetime price histories for both the new and used versions of the time.
But the best part is the ‘alert’ feature that allows you to set a price you would like to pay for the product and when the prices drops to it, you receive an alert.
Tracktor is a free Google Chrome extension or you can use the stand alone price tracking from the Tracktor web site
