How this helps you
You stop checking shop pages yourself, and the only alert you get is one you can act on.
Check the price of [exact product] at [shop links]. Only count the exact configuration. For each shop give: price, in stock yes or no, and the time checked. If a page won't load or the price isn't shown, write unknown; never guess. Message me only if a price is verified below [target price]. Then set this as a routine every day at [time].
Fill in: [exact product] is the full model name and configuration. [shop links] are the product pages. [target price] is your trigger, or the current lowest price. [time] is when it runs.
What they did
Parker Prompts wanted a specific laptop (exact model, memory and storage) below its current price. He made a Bot called Air Watch with a price watch label, and its description says to monitor two retailers and alert him only when it verifies a lower price for the right model and configuration. In a test it reloaded both sites several times over about five minutes. One shop's price stayed the same and the other shop's offer area failed to load every time. The Bot recorded that as unknown instead of guessing a discount or saying it was out of stock, and sent nothing. He then scheduled the check for 9:00 every morning.
Who it's for: Anyone waiting to buy something specific, and small businesses tracking a supplier's price.
Before you start
- The exact product: model, size, colour, memory, whatever changes the price.
- The product page links at the shops you trust.
- Your target price, or 'any drop' if you just want to know.
How to try it
- Create a new Bot (Parker calls his Air Watch) and give it a label such as Price watch.
- Put the standing rules in its description: the exact product, the shops, alert only on a verified lower price, and anything it can't read counts as unknown.
- Paste the prompt below for a first scan and read its table. Check that it found the right configuration on each page.
- Ask it to retry a page that fails, so you see how it reports unknown in real life.
- When you're happy, ask it to run the same check every morning at a time you choose.
What to expect
Most mornings: nothing. On a run where a shop has dropped below your target, one message with the shop, the new price, the link and the time it checked.
Common mistakes
- Naming a product family instead of one configuration. The cheapest listing is often a different model.
- Letting a failed page count as a change. Unknown should mean silence, not an alert.
- Asking for hourly checks. A daily check is enough for most purchases and costs far less usage.
Related tips
- Research to purchase, with your approval: It researched pet insurance, compared quotes and paid with Link only after the user said buy.
- Put quiet hours inside the routine itself: Have the routine re-check the clock right before it acts, and skip itself if it's too late.
- Compare tools from their official pricing pages, into a shareable sheet: Ask a Bot to compare a few products for your team size using only the official pricing pages, with no signing in, and return a table plus a spreadsheet in your library.
- Have a Bot watch for cancellations at a fully booked spot: Ask a Bot to check a booking page every hour and ping you the moment a slot opens, so you can grab a cancellation before anyone else.
- Let your Bot cancel free trials and unused subscriptions: Three built-in templates from 0.78: start a trial and cancel it before it bills, cancel plans you don't use, and watch renewal prices.
