# Track a price and buy when it drops, paying yourself

Job: [Buy a specific item once it falls to your target price, without the agent spending for you](https://aiagents.org/canai/track-a-price-and-buy-when-it-drops)

## Need

- ai agent: [ChatGPT or Claude](https://aiagents.org/agents/chatgpt-or-claude), [ChatGPT agent or Claude in Chrome](https://aiagents.org/agents/chatgpt-agent-or-claude-in-chrome)

## Steps

1. Pin down the item: model number, variant, condition, which shops and sellers are acceptable, and your ceiling including shipping and tax.
2. Decide how to monitor it: for a single item or two, check in weekly with a chat assistant; for many, have a coding agent build a tracker.
3. When a reading looks good, open the shop page yourself and confirm the price, variant and seller, since trackers misread pages.
4. Tell the agent the one offer you accept and have it read back the link, variant, seller and price.
5. Have a browser agent add the item and go as far as checkout (or do this step manually), then confirm the total and complete payment yourself.
6. Note: Do not save a card in the agent's browser or let it press the final buy button; you complete payment yourself.
7. Note: The steps are restated in our own words from the Agents Handbook page (CC BY 4.0); its prompt is linked, not copied. Repeat weekly, or at each tracker alert, until you buy.
