We've developed a free plugin for Amazon Product Finder to help you track prices. You can access Amazon Product price history on any product in the United States.

With this extension you can check out price history and see the price of any product at any time. You can also choose any time period, choose from 1 day, 1 month, 1 year, 5 years, 10 years, 20 years and more.

No account needed, no login required, just install the app and start browsing.

Another handy features is that you can view the prices of any product with any category and subcategories. You can drag to view all time periods.

If you're in the US, you can also view the lowest price of the item on Amazon, as well as its date of publishing.

All the features are available to users with free accounts and to those who're on a paid account. Amazon Product Finder can be installed on almost any device, including computers and tablets.
