Buy and sell items for your balance, from $0.01 to $100,000. The buyer pays the listed price; the seller gets it minus the 5 % market fee.
The money and the item change hands in one step. You can cancel a listing while it is for sale.
Buy orders name a price for up to 100 of an item. The money is held until the order fills or you cancel it. An order first buys any listing at or below its price, and a new listing at or below the best order sells to it at once.
Each item page shows recent sales and the median price.
