Keepa for Firefox

Amazon.com is one of the biggest e-commerce retailers out there, and it comes with a very large selection of products. And, in case you buy often from their online store, the Keepa extension is a must-have for you.

This Firefox extension provides an comprehensive way to track the products you like and catch the best deals. With its intricate price and overall market analysis, Keepa can save you hundreds, if not thousands of dollars, over time.

Even if you only rarely use the Amazon services, Keepa should still be a top priority addon for you, and it will surely become indispensable after you get used to, before buying anything else, always checking the price history feature.

After you click the extension's toolbar icon, a new tab will open where you can set and manage all of the tracked products. In the Deals tab, you will find everything that is on sale or the newest deals added from Amazon.

You can pick what deal type to be displayed from the panels on the right. There are options to even set the price and the discount range, or the minimum ratings the products must have.

Whenever you click on a page, you will open a new window that will give all the necessary details. The first thing you'll see there is the price history and its evolution in the period of time you set.

If you decide to track the product, in the second tab you can manage how the tracking will take place. You can pick from 3 types of tracking (Basic, Advanced and Pro), choose the notification options and even set the price margin you wish.

In the same panel, you can set the tracking period and write a memo, in case you want to remember something about the respective product you add to your tracking list.

In the Data tab, you will have in-depth information about your tracked product, as well as current and average sales rank, review counts and list prices.

With so many product details provided and multiple ways to customize how the tracked items are shown, via the filters you set, Keepa is something that cannot be missed, as the value it brings can hardly be matched by other addons.
