AliExpress Price Tracker – free Chrome extension (InstaShop Price Check)

InstaShop – Price Check is a free Chrome extension that shows, right on any AliExpress product page, the product's real price history in ILS, whether today's price is good, normal or higher than usual, and sends you an alert when the price drops. No made-up "was" prices – only prices we actually recorded.

What you see on every product page

• Price and verdict – a small button in the corner: price, "good / normal / higher than usual" and how long the product has been tracked.
• Price chart – every recorded day, from the first day we tracked the product.
• Lowest, median and highest price we saw.
• Price-drop alert – add a product to your watch list; every 6 hours the extension checks it and notifies you of a drop of 3% or more.
• Similar, cheaper deal – only when we find a product with a similar title that is at least 10% cheaper, rated 4.3+ with 50+ orders.
• Discount check – was the "original" price AliExpress shows ever actually recorded, or is the discount inflated? How common are inflated discounts? Full report.
• What similar products cost – the usual price range of the same kind of product.
• Seller coupon code – when there is one, with a copy button.
• Badges in AliExpress search results – "good price" or "higher than usual" on products we already track.
• Price matches in Google search (optional, from v1.2) – search for a product on Google and see in a corner card if it is on AliExpress and for how much. Off until you turn it on.

How the verdict works (the exact rule)

Where the data comes from

Daily prices of 9,332 catalog products from the AliExpress Affiliate API (32 tracked days since 28 Sep 2026), plus every product a user opens, which then enters daily tracking. On the page itself, the extension uses the price AliExpress shows (in ILS), so temporary sales like SuperDeals are reflected. Full method: how we track prices.

Privacy and honesty

• Only the product ID is sent – no name, email, user ID or browsing history. Your watch list stays in your browser.
• Affiliate links only on your own click, clearly labelled. The extension never rewrites links, never adds cookies and never replaces other people's affiliate tags.
• Not affiliated with AliExpress or Alibaba. Privacy policy · Terms · Support

FAQ

What does the InstaShop Price Check extension do?

On AliExpress product pages it shows the price history in ILS, a "good / normal / higher than usual" verdict, the lowest, median and highest price seen, and lets you get an alert when the price drops.

Is the extension free?

Yes, completely free. InstaShop earns only when you click "Similar, cheaper deal" and buy – that is an affiliate link, at no extra cost to you.

How is the verdict calculated?

Only after at least 7 tracked days. "Higher than usual" – when on at least 60% of the days the price was more than 2% lower than today. "Good price" – when today's price is within 2% of the lowest price we saw. Otherwise – "normal price".

Why does the extension price sometimes differ from the InstaShop catalog?

The extension reads the price shown on the AliExpress page (in ILS), including sales such as SuperDeals. The AliExpress API that refreshes the catalog daily returns the regular price, without temporary sales or personal discounts.

What data does the extension send?

The ID of the product you open, to return its price history; your watch-list product IDs every 6 hours; and the price shown on the page once a day per product ("share prices anonymously" – can be turned off). Only if you enabled the Google option – also your search words, which are not stored. No name, email or user ID. Your watch list stays in your browser.

Does it change links or add cookies?

No. It never changes links, never adds cookies and never touches other people's affiliate links. An affiliate link opens only when you click an offer yourself, and none is shown on pages you reached through someone else's affiliate link.

Which browsers are supported?

Google Chrome on desktop (and Chromium browsers that install from the Chrome Web Store). Chrome on mobile has no extension support – use the web price checker instead.

How do I know if an AliExpress discount is real?

The extension compares the "original" price on the page with the prices we actually recorded. If we never saw that price (after at least 7 tracked days), or it is far above what similar products cost, you get a warning. Our report found that for most claimed discounts the original price was never seen.

Does it work in Google search too?

Yes, as an optional feature from v1.2: turn it on in the extension popup, Chrome asks for access to Google, and when you search for a product a small corner card shows matching AliExpress products. Search words are not stored, and you can turn it off any time.
