As people report it

  1. Get these ready

    • The item or booking you want, with a link or photo
    • The price you've already found
    • An email account the bot can send from, if it should ask for a better rate

    Check first: Check the refund terms and any restocking or return shipping fees. Accepting store credit can end your claim for cash.

  2. Give the bot this prompt

    To Grok Bot STARTING PROMPT, ADAPTED

    I want to buy [item or booking] and the best price I've seen is [price] at [store or site]. Search other stores and sites for the same item, or ask the seller or hotel by email for a better rate, and list the best offers with the total price including shipping, fees and taxes, plus each seller's return or cancellation policy. Don't buy, book or pay for anything until I approve it, and never enter card details yourself. Tell me which prices you saw on the seller's own page and which came from search results.

    Written for this site from what the cases below did. It is a starting point, not a prompt anyone posted. Fill in the parts in brackets.

  3. Stay close for these

    • Approve the offer before anything is bought or booked
    • Pay at checkout yourself
    • Check the final total and the return terms

    Worth watching for

    • A cheaper listing can be a different model, a used item or a reseller
    • Shipping, fees and taxes can wipe out the difference
    • A lower hotel rate can come with stricter cancellation terms
