Buyers ask the seller a question directly on the item page. The seller gets a notification, answers in the members area, and the question and answer appear publicly on the page for all other buyers.
A buyer with an unanswered question rarely bids. Public Q&A answers those questions once, for everybody, and makes the listing more complete with every answer.
Because the answers are public, they also build trust: bidders see that the seller is responsive and transparent.
Together with the AI lot assistant and private messages, buyers always have a fast way to get the information they need.
