If the option is available you can use “Buy Out” to purchase the item immediately without having to place a bid. Some sellers 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, you will be asked to confirm your intention to buy out the item before the sale is concluded. Buy out’s cannot be retracted.

The term 'Buy Out' is pretty much the same as ebays 'Buy It Now' feature.
