1. CamelCamelCamel

It’s as simple as copying the page URL for the item in question and pasting into the search tool at the very top of the page. Hit the search button and watch the CamelCamelCamel magic. You’ll see info about the product and a purchase button as well as a detailed price history going back months or even years.

2. Keepa

Keepa also offers its own browser extensions for FireFox, Chrome and Microsoft Edge. Wishlist importing is available with Keepa as well for email updates when prices drop. Keepa works in nearly a dozen locations around the world, including the UK, Spain, Japan, France and Australia. As a bonus, Keepa highlights support for tracking lightning deals, which is very welcomed, given how quickly they sell out.

3. Honey

Once it’s installed, you can either register with an email address or just click ‘I’ll sign up later’ at the bottom of the page (though if you want to use the droplist to track prices, you should register). The price tracking and history aren’t as detailed as other sites on this list, but what really separates Honey from the competition is coupons. The company prides itself on searching the Web for coupons or promotional codes. Another Honey’s attractive features is its ability to instantly apply coupons to any product if available.
