If the option is available you can use “Buy Out” or "Buy-it-Now" to purchase the item immediately without having to place a bid. Buy Out is the same thing you might be familiar with on eBay as a buy-it-now feature. Sellers may offer such an option, which can be used at any time until a bid has been placed over any applicable reserve price.
The “Buy Out” option will appear on the item details page. If you select this option as a buyer, you will be asked to confirm your intention to buy out the item before the sale is concluded. Buy out’s cannot be retracted and buying an item under the buy out or buy-it-now option is considered a legal and binding sale.
