Every listing is one seller's offer
eBay has no buy box: a listing is a single seller's offer, so the seller block describes whoever posted it rather than whoever is currently winning. Sellers carry a positive-feedback percentage instead of a star rating, so seller.rating is null here and seller.feedback_percent carries the number.
