How to get an alert when a product is back in stock

By the ChangeGist team · Updated 3 November 2026 · 5 min read

The thing you want is sold out, and the shop's “notify me” button either doesn't exist or never seems to email you. Here's how back-in-stock alerts work, why they sometimes fail, and how to set up one you can rely on.

Start with the shop's own alert

Many shops have a “notify me when available” button. Use it, it's free. Just don't rely on it alone. Some shops send these emails in batches, some only send them for certain sizes, and some emails land in spam.

Why watching the page works

When a product comes back, the page changes. The button switches from “Sold out” to “Add to basket”, a stock count appears, or a size becomes selectable. A change monitor notices that change and tells you, whatever the shop's own system does.

How to set it up well

What it can't do

Page monitoring can't reserve the item for you, and it won't see stock that's only visible after logging in. For very limited drops that sell out in seconds, no alert is fast enough to guarantee you get one.

Tips that help you actually get it

Beyond shopping

The same approach works for anything where availability shows up on a public page: event tickets released in batches, course places, public appointment slots and limited editions.

How ChangeGist handles it

Paste the product link, open Advanced options if you want to watch just the buy button, and pick how often to check. When the button or stock message changes, you get an email that says what changed, such as “Button changed: Sold out → Add to basket”.

Be considerate

Only watch public pages, keep checks at a reasonable pace, and remember that some big marketplaces limit automated visits in their terms.
