Price history: how to see what a product used to cost on any store

A price history shows what a product cost before today, which is how you tell a real discount from a relabeled one. Amazon items and some products in Chrome already have a record you can read in seconds, but for brand stores, small shops and software plans nobody kept one, so the move is to start it yourself with AyeWatch on the exact page you plan to buy from.

Why past prices matter

A product page shows a single number: what it costs right now. A strikethrough "was" figure beside it says nothing about last month. With a few weeks of price history you can see whether today's offer is low for that item, how often the price moves, and whether waiting is likely to help.

The catch is that somebody had to record the price before you showed up. That happens for some stores and not for others.

Where price history already exists

Some detail on each:

• Keepa adds price history charts directly to Amazon product pages through its browser extension, on Amazon sites such as .com, .co.uk, .de and .co.jp.
• The Camelizer is the camelcamelcamel extension. Its toolbar icon pulls up past pricing for Amazon items in the US, Canada, Europe and Australia.
• Shopping Insights opens from Chrome's address bar on a product page. It needs a Google sign-in, synced history and a supported country: Australia, Canada, India, Japan or the US.
• The Wayback Machine lets you enter a URL and browse archived copies by date. Pages behind a login, blocked by robots.txt or built with heavy JavaScript often have gaps.

The gap nobody fills

Brands that sell direct, regional chains, specialist dealers and software pricing pages rarely appear in those tools. A brand can run a one-day sale on its own checkout and no chart anywhere will show it. If that is where you buy, the only history you will ever have is the one you start.

Start your own price history with AyeWatch

AyeWatch does not draw a chart of old prices. It reads the product page you paste on a schedule and tells you in plain words when the price changes, for example that it fell from one figure to another. Every update stays in your feed with its source link, and the daily digest gathers them under a date, so a dated record builds up from the day you begin.

1. Open the product and choose the exact variant first, such as size, color or storage, so the link shows the price you would pay.
2. Paste that link into a new webpage monitor.
3. Write the rule in plain English, such as "tell me about any price change on this page" or "alert me below $300".
4. Keep the pace on Auto, which checks more often while a page is busy, or pick your own interval.
5. Choose where alerts land. Push and the in-app feed are on every plan; email, Slack, Discord and webhooks need a paid plan.

The price has to be public. If a store only shows it after you log in, AyeWatch cannot see it either. Stock is a different event, so give availability its own monitor if both matter to you.

There is a free preview with no credit card, and paid plans start at $9 a month as of November 2026, billed in monitoring credits. Compare the AyeWatch plans before you pick one.

When another tool is the better choice

If all you want is an Amazon chart going back months, Keepa or The Camelizer will answer faster, because they were recording long before you arrived. For everything off Amazon, and for one habit across every store you use, AyeWatch is the tool to set up.
