Buy It Now
A fixed-price listing format where the buyer purchases immediately at the listed price, no bidding involved. The default and most common format for resellers because it's predictable — you set the price, the buyer pays it. On eBay, you can combine Buy It Now with Best Offer to allow negotiation.
