Back in stock alerts: store button, tracker site or your own watcher
The store's notify-me button is free but runs on the store's timetable. Tracker sites cover popular products. A watcher on the product page covers the rest.

Back in stock alerts come from three places: the store's own notify-me button, a tracker site that follows popular products for you, or a watcher you point at any product page yourself. For most people the best setup is the third, using AyeWatch on the exact listing, with the store's button switched on as a free backup.
Here is how the three compare and when each one is the right call.
The three options side by side
| Store's notify-me button | Tracker site such as NowInStock | Your own watcher with AyeWatch | |
|---|---|---|---|
| Which products | Only that store's listings | The hot products the site chooses to follow | Any public product page you paste |
| Which stores | One | Several retailers per product | As many as you add |
| Who decides when you hear | The store | The site | Your monitor and its rule |
| Cost | Free | Free with an account | Free preview, paid plans from $9 a month |
The store's button
It takes one tap, so use it. The catch is that the store sends that message on its own timetable, and on a product that sells out fast it can arrive after the stock has gone again. It also only tells you about that one shop, while the item may come back somewhere else first.
A tracker site
NowInStock describes itself as a free service that monitors online retailers for products coming in stock or up for preorder. You register, add the items you want from its trackers, and switch on alerts for each one. Its Pokemon cards tracker, for example, covers items sold at Amazon, Target, Walmart and Best Buy.
It is a good fit when the thing you want is already on its lists, such as graphics cards, consoles or trading cards. If it is not, you can suggest the product, but you are waiting on someone else to add it.
Your own watcher
This is where AyeWatch comes in. You paste the product page, pick the exact variant first, and write what should count, such as "Alert me when this can be added to the cart. Ignore banners and related products." AyeWatch reads the page against that sentence and sends a short summary when it matches. It works on niche shops, small brands and odd items that no tracker site follows, and you can add the same product at several stores as separate monitors.
Alerts arrive as push notifications and in the app's feed on every plan, on the web, iOS or Android. Paying adds email, Slack, Discord and webhooks. The restock alerts guide from AyeWatch explains which page changes should count and which should not.
When the store's button is enough
If the product is not in high demand, say a refill, a spare part or a basic shirt in your size, the store's email will probably arrive in time, and you do not need anything else. Your own watcher earns its place on items that sell out within the hour, or when the store has no notify-me button at all.
What none of them do
None of these buy the item for you. An alert gets you to the page; you still have to check out, and automated bots will win the occasional launch that sells out in seconds. Being signed in with your address and payment saved helps more than any extra alert.
To try it, the AyeWatch free preview needs no card.
