What they did
A collector scheduled a Grok Bot "Pokémon deal finder" to scan eBay UK for auctions ending soon and Buy It Now listings, and to flag PSA 10 cards priced at least 20% under market.
How it went
One morning it alerted him to a matching auction, which he shared on X. He doesn't say whether he won it.
Worth knowing
- Self-reported X post; it doesn't explain how the bot works out the market price.
- The post doesn't say if he bought the card.
Prompt

Every morning, search eBay UK for PSA 10 [set or Pokémon] listings: auctions ending in the next [24 hours] and Buy It Now. Compare each to recent sold prices and alert me only when one is at least 20% under market. Include the link, price, recent sold average and time left.
