Keepa - Amazon Price Tracker

Keepa, Amazon price tracker which is a free extension for New Edge, can tell you whether products' best-buy price was available earlier or is just another gimmick.

With this shopping friendly extension, you'll see there are the price history and its evolution in the period of time you set for over 280 million Amazon products, even for different versions, colors or sizes of a product.

You can easily import your whole wishlist and create price watches for every item on it. You will have in-depth information about your tracked product, as well as current and average sales rank, review counts and list prices. And it will send you a price alert once the price of your tracked product drops below your desired price. Keepa can send you an email, leave a (private) post on your Facebook wall, Tweet you or simply show a desktop notification.

There is no account needed, just install and start saving money.
