Outcome

George Liu bought two Samsung phones from Best Buy, one for themselves and one for their father, and noticed a 30-day price match policy covering drops at Best Buy or major competitors. They spent 15 minutes building a Claude Cowork skill, gave it the model number and told it to check Best Buy, Amazon, Costco and a few other retailers every morning at 7 AM. One morning it found a quiet $20 drop on Best Buy's own product page: not a coupon or a sale, just a lower price. They opened Best Buy's chat, its AI walked them through the price match and a human agent approved a refund of $40 plus tax for the two phones.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing or a rule below tells you to.

Goal: Watch the price of something I've just bought and tell me if I can claim money back under the store's price-match policy.

Fill in before running:
- What I bought, model number, price paid and date: [DETAILS]
- The store and its price-match or price-adjustment window: [DETAILS]
- Which other retailers count under the policy: [DETAILS]

Rules:
- Check the store's official policy first and note the window and exclusions.
- Check the listed stores once a day for the exact same model, new and sold by the retailer itself.
- Alert me only when the price is lower and the claim still fits the policy, with screenshots and links.
- Draft what I should say to claim it; don't contact the store yourself.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A short alert with old price, new price, the difference, proof and the steps to claim.

You'll know it worked when: I claim the difference before the window closes.
