Amazon prices change constantly. One day an item is a bargain, the next it is back to full price. Amazon itself has no built-in price alert that lets you set a target price for any product. With the free tool Keepa you can set one up in two minutes and get a message the moment the price drops.
This guide starts with the short version for a quick price alert. After that, you will learn how to read the price history, which alternatives exist and how Amazon sellers use price alerts to find profitable products.
Amazon price alert in 3 steps: the quick version
- Install Keepa: add the free "Keepa - Amazon Price Tracker" extension to Chrome, Firefox or Edge, or download the Keepa app for iOS or Android. You can also use keepa.com directly in your browser.
- Open the product: go to the product page on Amazon.co.uk, Amazon.de or your marketplace. The Keepa price history chart now appears below the product description.
- Enter your target price: click "Track Product", enter your target price, confirm your email address the first time and click "Start Tracking". Done.
From now on Keepa watches the price for you and emails you as soon as it falls below your target. If you want to know which target price is realistic and how to never miss a price drop, read on.
What is Keepa?
Keepa is a price tracker for Amazon. It records the price history of products on the Amazon marketplaces and shows it as a chart right on the product page. According to its own website, Keepa now tracks more than 7 billion Amazon products worldwide. The real value is the alert system: you set a target price and Keepa tells you when it is reached.
Key features at a glance:
- Price history: separate lines for the Amazon price, Buy Box, new and used offers, often going back years
- Price drop and availability alerts: a message when a product hits your target price or is back in stock
- Multiple marketplaces: compare the same product on Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.it or Amazon.es
- Search by ASIN: on keepa.com you can find any product by its ASIN or Amazon link
- Seller data (Keepa Pro): sales rank, Buy Box history, number of sellers and the Product Finder
How to set up a Keepa price alert, step by step
Step 1: Install the extension or app
The Keepa extension is available for Chrome, Firefox and Edge. Search your browser's store for "Keepa - Amazon Price Tracker" and click "Add". There is nothing else to configure. As soon as you open Amazon, Keepa shows the price history right on the product page.
On the go, use the Keepa app for iOS or Android to search products, view charts and manage your alerts. Without installing anything, keepa.com works too: just paste the Amazon link or ASIN into the search.
Step 2: Open the product on Amazon
Go to Amazon.co.uk, Amazon.de or your marketplace and open the product you want to watch. For example, you have your eye on a laptop but only want to buy once it drops below £700.
Step 3: Read the price history
Below the product description you will see the Keepa chart. Take a minute here, because a good target price depends on how the price has behaved in the past. The most important lines:
- Orange: Amazon's own price, when Amazon sells the item
- Pink: the Buy Box price, which is what most customers actually pay
- Blue: the cheapest new offer from a third-party seller
- Black: the cheapest used offer
The chart tells you three things at a glance. If the price drops below your target every few weeks, your alert will trigger quickly. If it has only hit that price once in the past year, you may wait a long time. And if the price jumps up just before a "sale", the discount is often smaller than it looks. The price history exposes these fake discounts.
Step 4: Set up the price alert
- Click "Track Product" below the Keepa chart.
- Enter your target price, for example £700.
- Choose whether you want to watch new, used or both.
- Decide whether the alert covers only offers sold by Amazon or third-party sellers too.
- Pick how long to track, from one month to indefinitely.
- Click "Start Tracking". For your first alert, confirm your email address.
Step 5: Manage your price alerts
You will find all your alerts on keepa.com under "Track". It lists every tracked product with its current price and your target price. You can change thresholds, pause alerts or delete them. Check in now and then and clear out old alerts so the important ones do not get lost.
Step 6: Choose the right notification channel
How fast you hear about a price drop depends on the channel. You can set this in your Keepa account under "Notification Settings":
- Email: the default, reliable but easy to miss
- Push notification: via the app or browser, good for fast deals
- Telegram: lands on your phone instantly, ideal for Lightning Deals that are gone within minutes
Keepa alternatives: CamelCamelCamel and idealo
Keepa is the most complete tool, but not the only one. Two alternatives many shoppers use:
- CamelCamelCamel: a free Amazon price tracker with price history and email alerts, also for Amazon.co.uk and Amazon.de. The interface is simpler, but it is more than enough for a basic price alert.
- idealo price alert: compares many online shops, not just Amazon. Handy if you do not care where you buy, as long as it is cheap.
If you mainly want to watch Amazon prices and understand the history in detail, Keepa remains the best choice.
For Amazon sellers: price alerts as a sourcing tool
What is a bargain for shoppers is a buying opportunity for Amazon sellers. Many resellers use price alerts to buy products cheaply and resell them on Amazon at a profit. These Keepa features are especially useful for that:
- Compare prices across countries: price gaps between Amazon.co.uk, Amazon.de or Amazon.fr are often large and short-lived. That is exactly what Amazon-to-Amazon arbitrage lives on.
- Track sales rank: the sales rank history shows whether a product sells regularly or only now and then.
- Buy Box and seller count: if the number of sellers jumps sharply in a short time, the deal has spread and margins are shrinking.
- Product Finder: searches the whole catalogue by price range, sales rank, category and discount.
How to use this data for product research is explained in detail in our guide How to Use Keepa for Amazon FBA Product Research.
The difference: price alert or profit alert
A Keepa alert tells you that a price has dropped. Whether buying is worth it, you still have to work out yourself: FBA fees, referral fee, VAT, shipping. With 200 tracked products, that quickly becomes a full-time job.
That is what ProfitPath Price Alerts is for. You watch Amazon ASINs and products from more than 1,000 European shops in one list and set a minimum margin, minimum profit, ROI and monthly sales. You only get a message when a deal hits your target after all fees and VAT, via Discord in under 60 seconds, by email or in the app.
For quickly checking single products on Amazon or in store, use ProfitGo. The extension and app show you profit, ROI and fees in seconds.
How much does Keepa cost? Free vs Pro
Price history, the extension, the app and price alerts are free. For personal bargain hunting, that is all you need.
Keepa Pro costs €29 per month or €290 per year, around €24 a month. Pro unlocks the seller data: sales rank details, Buy Box history, the Product Finder and best seller lists. Older articles still quote €19 a month, which is no longer current. Check the price directly with Keepa before you subscribe.
The Keepa API for developers is a separate product and starts at around €49 a month.
Common Amazon price alert mistakes
- Unrealistic target price: if you pick a price the product has hit only once in two years, you will wait forever. Base it on the price history.
- Watching the wrong line: an alert on the cheapest third-party offer is not the same as an alert on Amazon's price. Pay attention to who you want to buy from.
- Email only: Lightning Deals are often gone before you read the email. Use push or Telegram for those.
- Buying blindly when the alert fires: look at the chart first. A price drop from a real sale looks different from a single seller clearing old stock.

Can I get notified of price drops on Amazon?
Yes. Keepa notifies you by email, push notification or Telegram as soon as the price falls below your target or a product is back in stock.
