## Key takeaways

- A Best Buy stock tracker has to pick the right buy button, handle bundles and variants, survive page redesigns and avoid repeat alerts.
- AyeWatch replaces selectors with a plain-English rule and sends restock alerts by push, or by email, Slack, Discord and webhooks on paid plans.
- Paid AyeWatch plans, from $9 a month as of November 2026, include a REST API and an MCP server for creating monitors from code or an AI assistant.

A Best Buy stock tracker is a job that loads one product page on a schedule and pings you when the item becomes purchasable. A developer can write one in an evening, but keeping it accurate is the real cost, so for most people the better choice is AyeWatch: paste the listing, state the condition in a sentence, and receive the alert by push, or by webhook into your own tools on a paid plan.

## What a homemade checker has to get right

The first version of a stock script is short: fetch the page, look for a string, send a message. The next versions are where the time goes.

- **Picking the right signal.** A product page has more than one button. Accessory carousels, protection plans and bundles all carry their own buy buttons, so matching on the words "add to cart" alone gives false positives.
- **Bundles and variants.** AyeWatch's [restock notes for Best Buy](https://ayewatch.ai/blog/best-buy-restock-alerts) warn that an item can come back only inside a bundle. A checker needs to know whether that counts for you.
- **Markup drift.** Retail pages get redesigned. A selector that matched in the spring may match nothing by Black Friday, and a silent script looks exactly like a quiet product.
- **Pace and manners.** Too slow and you miss a short restock. Too fast and you put load on someone else's site for little gain.
- **Delivery and noise.** One restock should mean one alert, sent somewhere you will see it, and not a message every minute while it stays in stock.
- **Uptime.** A script on a laptop stops when the lid closes.

## Script or watcher, job by job

| Job | Your own script | AyeWatch |
| --- | --- | --- |
| Schedule checks | cron or a loop you host | Auto pace, or a custom interval your plan allows |
| Decide what counts | selectors and string checks you maintain | a rule written in plain English |
| Explain the change | whatever your code logs | a short summary of what changed |
| Send it | your own push, email or Discord code | push and feed on every plan; email, Slack, Discord and webhooks on paid plans |
| Keep it running | your machine or server | runs on AyeWatch's side; manage it on web, iOS or Android |

## Writing a rule that holds up

The rule is where a watcher beats string matching. Something like "Tell me when the 16GB model can be bought on its own. Ignore bundles, open-box and accessories" describes intent rather than markup, so it does not hang on a CSS selector that the next redesign can break. Copy the exact variant's URL first; color and capacity often live on separate listings.

## Wiring it into your own stack

Every paid plan includes the AyeWatch REST API. You can create, list, update and delete monitors, and receive signed topic.update webhook events that carry an AI-written summary. That is enough to post restocks into a team Discord, log them to a sheet, or trigger your own script.

There is also an [MCP server](https://ayewatch.ai/documentation/mcp), so an AI coding assistant can create monitors for you. Its create_topic tool takes web page URLs plus a custom interval or Auto mode, and the MCP and REST calls share your API key's rate limit. A list of product links can become a set of monitors from one request.

## When your own script still wins

Write your own if you want to record every reading for a price chart, need parsing logic no rule can express, or already run monitoring infrastructure. AyeWatch reports changes; it does not keep a price history chart, and it does not check out for you. Keep your Best Buy account signed in, with payment and pickup choices set, so the alert turns into a purchase.

AyeWatch has a free preview with no card required, and paid plans start at $9 a month as of November 2026.

## Frequently asked questions

### Can I get Best Buy restock alerts in Discord?

Yes. AyeWatch's paid plans can send alerts to Discord, Slack, email or a signed webhook, so a restock on a watched Best Buy listing can post straight into a server.

### Does a stock tracker buy the item for me?

AyeWatch does not. It reads the public product page and tells you what changed, and you check out with your own Best Buy account.

### Should I write my own Best Buy stock checker?

Write one if you want every reading stored for your own charts or need custom parsing. If you only want to know when an item can be bought, a watcher with a written rule is less to maintain.
