Pick one offer yourself, let the agent add it to the cart, and take over for shipping and payment. Testers report agents that found an item quickly and stopped at payment, and also big shops that blocked the agent. **Outcome:** You see a short list of real offers for the exact item, and you pay for the one you chose on a site you trust. - Trust: **Corroborated**. Two or more public accounts from different people or sites describe the same job. - Runs: No community run reports yet. - Agents: ChatGPT agent, Claude in Chrome, Perplexity Comet - Category: Shopping and errands - Difficulty: beginner ยท Time: 10-30 minutes - Risk: medium. This job ends in a purchase. Agents can land on resellers or lookalike listings, so check the seller, the exact item and the total yourself, and enter payment details yourself. ## Human checkpoints - Approve the offer (shop, seller, exact item, total with shipping) before the agent adds anything to a cart. - Enter shipping and payment details yourself on the final page. ## Prompt (ChatGPT agent) Replace every [placeholder] before you run it. ```text Find [exact product name, model or variant, size, colour] for delivery to [ZIP code / city] by [date]. Maximum total including shipping and tax: [USD 60]. Only buy from these shops or the brand's own store: [list]. Skip marketplace sellers with fewer than [100] ratings, and skip anything described as used, open box, bundle or "similar". Step 1. Check stock at each shop. For each offer give: shop, seller name, exact item title as listed, price, shipping, delivery estimate, return policy, and the link. If a shop blocks you or asks for a login, note it and move on. STOP and show me the offers. Do not add anything to a cart yet. Step 2. When I pick an offer, add exactly [1] of that item to the cart and go to checkout. Use guest checkout unless I log in myself. STOP at the shipping and payment step. Read back the item title, seller, quantity and total from the page. Do not enter my address or card details. I will take over and pay. ``` Other agent variants: [ChatGPT agent](https://agentshandbook.com/p/find-a-hard-to-find-product-and-stop-at-checkout.md?agent=chatgpt-agent), [Claude in Chrome](https://agentshandbook.com/p/find-a-hard-to-find-product-and-stop-at-checkout.md?agent=claude-in-chrome). ## What you need - **A browser agent such as ChatGPT agent, Claude in Chrome or Perplexity Comet** (app) - **A list of shops you trust** (data) - **A payment method you enter yourself** (data) ## Steps 1. **Describe the exact item.** Write the full product name with model, size and colour, your price limit including shipping, your delivery deadline and the shops you trust. - Check: Someone else could find the same item from your description. 2. **Let the agent check stock.** Paste the prompt. Watch the first few minutes. If a shop blocks the agent, let it move on. - Check: You get a table of offers with links and exact item titles. 3. **Check the offers yourself.** Open the link for your top offer. Compare the item title, seller and total with the table. - Check: The listing you opened matches the agent's table. 4. **Approve one offer.** Tell the agent which offer to buy and the quantity. - Check: The agent puts exactly that item and quantity in the cart. 5. **Take over and pay.** When the agent stops at shipping or payment, take control, enter your details and pay. - Check: You get an order confirmation with the right item, seller and total. ## What goes wrong - **A large shop blocks the agent again and again.** Fix: Put several shops in your list and tell the agent to note a block and move on. Check the blocked shop yourself. - **The agent cannot finish checkout without your address, login or card.** Fix: This is expected. Take over at that step and pay yourself. ## Evidence - [ChatGPT agent handles my most annoying tasks, and here's what actually surprised me](https://www.tomsguide.com/ai/i-tested-chatgpt-agent-on-5-everyday-tasks-heres-what-happened) (news, Amanda Caswell, 2025-07-28, ChatGPT agent): The reviewer asked the agent to find a hard-to-find collectible toy. She says it found the item in six minutes, added it to the cart, went to checkout and asked for shipping and card details, and she took control to finish the sale. - [OpenAI's Operator in action, what it can and can't do](https://www.vktr.com/ai-technology/openais-operator-in-action-what-it-can-and-cant-do/) (news, Michelle Hawley, 2025-03-11, ChatGPT agent): The reporter asked Operator, the predecessor of ChatGPT agent, to order 144 blue pens. She says Amazon blocked it several times, so it found a pack on Staples for $23.39, started a guest checkout and handed control back at payment. ## References - [Get started with Claude in Chrome (Claude Help Center)](https://support.claude.com/en/articles/12012173-get-started-with-claude-in-chrome) (checked 2026-10-13) ## Report your run After you run this playbook, report the result so the next agent starts from better data.
