Keepa browser extension can help you find the very best Prime Day deals

Amazon plans to host its Prime Day sales event on June 21 and 22 this year. Although the online retailer is expected to offer deep discounts, sellers usually tend to change prices often (or compare a discount to the original price), making it seem like you are grabbing a good deal, and this is when the Keepa extension can help you skip unworthy discounts.

Keepa is a freemium service that can track the prices of Amazon products. The service works best with its browser extension (for Microsoft Edge, Chrome, and Firefox) that embeds the information the price history on every product page. So if you find an amazing deal, you can review the price history to determine how it changed over time to help make a more informed decision.

While you can use the extension without even signing into Amazon, you'll need an Amazon Prime subscription to get those Prime Day deals. The membership goes for $119 per year (or $12.99 per month), but in addition to accessing the biggest discounts of the year, you also get many benefits, including free and faster shipping, access to the company's video, music, and gaming stream services, and many other perks. If you never used Prime before, the company also offers a free trial, which you can use to shop during the 48-hour event, and later, you can decide to continue or cancel the subscription.

In this Windows 10 guide, we will walk you through the steps to use the Keepa extension to view the price history of an Amazon product to shop with confidence during the Amazon Prime Day event.

How to check Amazon price history with Keepa

To check Amazon products price history with Keepa, use these steps:

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

The Price history tab shows a graph with the product's price history from Amazon and third-party sellers. However, you usually want to focus only on the information sold and fulfilled from Amazon, the orange graph.

The light purple graph shows the price history from third-party seller products. Also, by default, a dark graph displays the price for used items, and the 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 provides other pricing data, such as from 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 historical data for a specific product.

Once you review the data, you can determine whether the price was recently increased and then lowered to make it seem like you are getting a good deal. Or if the price has a great discount, but when compared to the original price, which may not be a good deal, if the regular price is in part with the Prime Day offering.
