How to track price drops across online stores

A practical 2026 guide

You found something you want, but not at that price. Instead of checking the tab every day (or buying now and regretting it during next week's sale), you can have the price watched for you. Here are the four main ways to track a price drop, and how to pick the one that fits how you shop.

1. Check the page manually

The zero-tools option: bookmark the product and revisit it every few days. It's free and works anywhere, but it's easy to forget, and by the time you remember, a short flash sale may already be over. Fine for one or two items; unworkable once your list grows.

2. Use the store's own alerts

Many retailers let you add an item to a wishlist or "notify me" list and email you about price changes or restocks. The catch: every store is a separate account, a separate inbox, and a separate set of rules. Track things across ten shops and you're managing ten different systems, and some smaller stores offer nothing at all.

3. Track prices with a browser extension

A price-tracking browser extension saves the product as you browse and can watch prices across stores in one place. You save with one click while you're already on the page, and the tool can re-check supported products in the background while the browser is available. Retailer blocking, signed-in pages, and sleeping devices can delay or prevent checks.

Why an extension beats manual checking: it captures the price at the moment you saved, so a "drop" is measured against what you saw, not a made-up list price, and it can keep checking supported products after you close the tab, as long as the browser is available.

4. Save and track with an app

If you shop on your phone, an app that hooks into the share sheet lets you save from Safari or any shopping app in a couple of taps, then sends a push notification when the price drops or a sold-out size comes back. The best setups sync with a browser extension so your list is the same everywhere.

How to do it with WindowShopping (step by step)

WindowShopping is a free browser extension for Chrome and Firefox. Its iOS app has been submitted to the App Store and is coming soon, pending approval. Until then, use Chrome or Firefox. Automatic monitoring is available where the retailer, product page, and device support it:

Save the product. On desktop, click the WindowShopping button on the product page. On the website, paste the product link and details are pre-filled when usable retailer metadata is available. Review and edit them before saving.
Drop it in a collection. Group saves however you like, "Wardrobe," "Gift ideas," "Someday", so your list stays readable as it grows.
Let it watch the price. For supported products, WindowShopping checks about once an hour while your browser is available. Price changes require two successful observations before a price alert is sent. Restock alerts require a confident match to the saved product or exact variant.
Buy on the dip. When the alert lands, open the item and head straight to the store to check out at the lower price.

Start saving in one click. WindowShopping is free and saves products across a broad range of supported HTTPS stores. Saving is separate from automatic monitoring, which depends on the retailer, product page, and device.

Tips for tracking price drops well

Save early. The sooner you save, the longer the tool has to catch a dip before you'd have bought anyway.
Watch stock, not just price. For popular sizes and limited items, a back-in-stock alert matters as much as a price cut.
Keep everything in one list. Scattering saves across store wishlists, tabs, and screenshots is why sales get missed. One place you actually check is worth more than five you don't.
