This year, Amazon Prime Day event is on October 13 and 14, and if you’re planning to shop, in this guide, we’ll show you the steps to use Keepa to check product price history to make sure you’re getting a good deal.

The Prime Day two-day shopping spree event will kick off on Tuesday, October 13, 2020, at 3 AM ET (12 AM PT). While the mega-online retailer is expected to offer hefty discounts on thousands of items, the company is known to lower and increase prices regularly, which can make it confusing to determine if you’re getting a good deal, and this is when Keepa comes in handy.

Keepa is a freemium service that tracks the price history of products available in Amazon, and it embeds the information as an easy to follow graph on every product you visit on the website using a browser extension available for Microsoft Edge, Chrome, and Firefox on Windows 10. If a discount looks tempting, you can review the data to understand how the price fluctuated over time to make a more informed purchase decision.

The sales event is only available for Amazon Prime members. If you don’t have a subscription, you can get a monthly pass for $12.99 or $119 for the yearly membership. Amazon will even let you try its Prime subscription for free, which you can use to shop on October 13 and 14, and then decide if you want to continue.

In this Windows 10 guide, we’ll walk you through the steps to use the Keepa extension on the most popular web browsers to understand the price history of an Amazon product to shop with confidence during the Amazon Prime Day event.

This guide shows you the steps to install the extension in the three most popular browsers, but Keepa is also available for Safari and Opera.

How to check Amazon product price history using Keepa

To get started checking price history for Amazon products, use these steps:

  1. Open Amazon on the browser.
  2. Sign in with your account (if applicable).
  3. Search for a product you want to purchase during Amazon Prime Day.
  4. Confirm the Keepa embedded information below the product description.
  5. Click the Price history tab.

The Price history tab shows a graph with the product’s price history in Amazon and third-party sellers. However, almost always, you only want to focus on the orange graph, since it shows the product’s information sold and fulfill from Amazon.

The light purple graph shows the price history of the product from third-party sellers. Also, by default, there’s a gray graph that displays the product’s price in used condition, and this data can be from Amazon or third-party sellers.

You can always toggle the views to focus on the price history from a specific type of seller.

The extension also offers a bunch of other data, such as from the Amazon Warehouse deals, third-party sellers with fulfillment by the merchant, different types of conditions, and more.

At the bottom, you can also change the range for the price to a “day,” “week,” “three months,” and the “all” option will show all the available historical data for that particular product.

Once you understand the information, if a pretty good deal shows up, you can check the price history to determine whether the regular price was recently increased and then lowered to build the illusion of a good discount.
