Keepa extension for Black Friday 2019Source: Windows Central

Black Friday 2019 sales may be over but all the good Cyber Monday deals are happening now. Online and physical retailers will be packed with great deals, but that doesn't necessarily mean that you'll be saving money on every purchase.

Amazon is one of those retailers known to change prices regularly, which makes it confusing (even more on big shopping days) to see if you're getting a good deal. Keepa is a freemium service that tracks the price history of virtually every item available in Amazon, and using the browser extension on Windows 10 will embed a graph with a history of the price for the product you want, which it'll help you make a more informed purchase decision this Black Friday.

In this Windows 10 guide, we walk you through the steps to install and use the Keepa extension on Microsoft Edge, Chrome, and Firefox, to understand how an Amazon price has fluctuated over time to shop with confidence during the Cyber Monday sales event and beyond.

Once you complete the steps, you can start using Keepa to see the price history for Cyber Mondah products, or to monitor Amazon products until they reach the price you're willing to pay.

How to see Amazon product price history with Keepa

After Keepa is installed on your web browser, you can get started with these steps:

  1. Open your web browser.
  2. Navigate to Amazon.com.
  3. Select the product you're interested in purchasing.
  4. Scroll down, just below the product description, to load the Keepa information.
  5. Click the Price history tab.

On the Pricing history tab, the single most crucial piece of information is the Amazon (orange) chart, which shows you the price history of the product sold and fulfilled by Amazon in the last three months (you can expand the view using the "Range" option on the right), allowing you to quickly find out you're getting a good deal.

The New (light purple) graph will also show you the price history for the product but from third-party sellers.

The Used (dark) graph will display the lowest price of a used product, and this information can be from Amazon or third-party sellers.

Also, the graph will show Amazon Warehouse deals, which don't happen every day, and as such, they appear with a purple X mark.

Once you complete the steps, you'll have a better understanding of the price history, which helps determine if you'll be getting a good deal during Cyber Monday 2019.

How to track Amazon product prices with Keepa

You don't need to create a free account with the service, but if you want to track products and receive alerts as soon as a product drops to your desired price, you'll need to sign up with Keepa.

  1. Open Keepa.com.

  2. Navigate to Amazon.com.
  3. Select the product you're interested in purchasing.
  4. Scroll down, just below the product description load the Keepa information.
  5. Click the Track product tab.

  7. Specify the desired price you wish to pay when the product is sold by a third-party product.

    Quick tip: Set the desired price a little above the amount you want to pay. This way, if the price drops, and it's just above the price you're willing to pay, it may still be a good buy. You don't want to miss a good deal because of a few bucks difference.

  8. (Optional) Specify the desired price you wish to pay when the product condition is used.
  9. Use the Track for drop-down menu to select how long you want to track the product price.
  10. Click the Start tracking button.

After you complete the steps, Keepa will monitor the price for the product, and you'll receive an email as soon as it reaches your desired amount.

If you are monitoring multiple Amazon products during Cyber Monday 2019, you can also see all your tracked products in your Keepa account online.

How to change Amazon price tracking settings using Keepa

Keepa also allows you to customize several aspects of the extension on your web browser to make tracking prices on Amazon even easier, including settings to update the chart appearance, options to define default tracking settings, and extension style.

Once you complete the steps, you need to refresh the page to apply the new settings.

This guide is focused on Windows 10, but because it's a browser extension, you can also use Keepa in the equivalent versions of the supported browsers in older versions of Windows, macOS, and Linux.

Although Keepa provides a subscription plan to access advanced features, the free tier should be more than enough for anyone who just wants to get some price history information to spend money wisely and track several items during the Cyber Monday sale event.
