Price history checker: the right one for each kind of store

The best price history checker depends on the store: for Amazon items use Keepa or The Camelizer, and for everything else use AyeWatch, because no checker holds old prices for brand sites, small retailers or software plans. If you shop in more than one place, start with AyeWatch, since it covers any public product page from the day you add it.

Which price history checker should I use?

Match the tool to where the product is sold.

How do I check price history on Amazon?

Install one of two browser extensions. Keepa draws its chart right on the Amazon product page and lets you set watches that fire when an item falls below your target or comes back in stock. Its listing names Amazon domains from the US and UK to Japan, India and Mexico.

The Camelizer comes from camelcamelcamel. You press the camel button next to the address bar to see the item's historical pricing, or set a watch and get an email when the price falls. It lists Amazon in the US, Canada, Europe and Australia.

How do I check price history on other sites?

Try Chrome first. On a desktop product page, a Shopping Insights button can appear in the address bar; it opens a panel with the price history and the usual range, variants like color or storage included. It only works when you are signed in to Chrome, sync your history and live in one of five countries: Australia, Canada, India, Japan or the US.

If Chrome has nothing, paste the URL into the Wayback Machine and press Browse History. You may find dated copies of the page with the old price on them. Expect holes: crawlers miss pages they never found, and pages behind passwords or blocked by robots.txt are not archived.

What if no checker has the product?

Then there is no past record to find, and the useful step is to begin one now. That is where AyeWatch fits. You paste the product link, say what you care about in plain English ("any price change" or "below $150"), and AyeWatch reads the page on its schedule. When the price moves you get a short summary saying what changed, with the link, and each one stays in your feed. It does not draw a chart, and it cannot read prices a store only shows after login.

Alerts reach you by push and in the feed on every plan; paid plans add email, Slack, Discord and webhooks. You can start a monitor on the free preview without a card, and paid plans begin at $9 a month as of November 2026.

Is a price history checker worth using?

Yes, for anything you would buy anyway. A sale label compares against a reference price the store chose. A history, even a short one you started yourself, shows what the item was listed at before, which is the comparison that matters.

When is AyeWatch not the right pick?

If you only shop on Amazon and want months of data today, Keepa or The Camelizer is the quicker answer, since they were collecting before you looked. Once your list spans several stores, AyeWatch is the one tool that covers all of them.
