Amazon price history checker: read the chart before you click buy
Keepa and The Camelizer show an Amazon item's past prices in a click, Chrome adds a cross-store view, and AyeWatch covers the stores Amazon tools never see.

An Amazon price history checker shows what an item has sold for on Amazon over past weeks and months, so you can see whether today's deal is actually low. Keepa and camelcamelcamel's Camelizer extension do this in a click, and the best overall setup pairs one of them with AyeWatch, which alerts you when a price changes on the other stores in your cart.
The checkers at a glance
| Checker | Where you see it | Alerts | Amazon sites listed |
|---|---|---|---|
| Keepa | A chart on the product page itself | Below your target, or back in stock | .com, .co.uk, .de, .co.jp, .fr, .ca, .it, .es, .in, .mx |
| The Camelizer | A pop-up from the camel toolbar icon | Email when the price drops | US, Canada, Europe, Australia |
| Chrome Shopping Insights | A side panel in Chrome | Tracked items go to your Shopping list | Not tied to Amazon; five countries |
Check it with Keepa
- Add the Keepa extension to your browser. Its store listing says you do not need an account to start.
- Open any Amazon product page. The price history chart shows up on the page itself, so there is nothing else to open.
- If you want a ping, set a price watch with your target price. Keepa can also tell you when an item returns to stock.
Check it with the Camelizer extension
- Install The Camelizer from your browser's extension store.
- On the Amazon listing, click the camel icon.
- Read the historical pricing, or create a watch so camelcamelcamel emails you when the price falls.
Check it in Chrome
Chrome's Shopping Insights is not an Amazon tool, but it is a useful second opinion. If a Shopping Insights button appears in the address bar on a product page, it opens a panel with that product's price history and price range across the web, which shows whether Amazon is cheap compared with other sellers. You need to be signed in to Chrome with history sync on, and the feature is limited to Australia, Canada, India, Japan and the US.
How to read the chart
- Compare today's price with the low points of recent months, not with the crossed-out figure on the listing.
- Look at how often the line dips. Frequent dips mean waiting tends to pay; a flat line means today's price is the price.
- Check you are on the right variant. Another color or capacity can carry a different price and a different history.
- If you are close to your number but not there, set the alert and walk away.
For the rest of your list, use AyeWatch
Amazon is only part of most carts. The headphones on the brand's own store, the chair from a regional chain and the app subscription you are about to renew sit outside every Amazon checker. AyeWatch covers those. Paste the public product page, write the rule in plain English, for example "alert me if this drops under $200", and AyeWatch reads the page on Auto or on the interval you choose. When the price moves it sends a short summary of the change with the link, and the update stays in your feed.
It does not keep a chart, buy anything or see prices hidden behind a login. Alerts come by push and in the app on every plan, with email, Slack, Discord and webhooks on paid plans. You can try it on a free preview with no card; paid plans start at $9 a month as of November 2026, billed in monitoring credits.
AyeWatch's own Amazon guide points Amazon-only shoppers to these same history tools. That is the honest trade-off: if your cart is all Amazon, Keepa or The Camelizer may be all you need. Once it spreads across stores, add AyeWatch so one alert habit covers every page.
