This auction type allows for the sale of individual quantities of an auction but the price that everyone will pay for their items is not determined until the auction closes. Basically all winners will pay the same price but the highest bidder will be first assured of winning their quantity bid on of the auction. This process loops through the next highest bidder where they win their quantity bid on and so on until all items are "won". The last winning bidder may not win the full quantity they bid on. They are the last winning bidder because their quantity is equal to or greater than the quantity left after all other higher bidding winners have won their quantity bid on. The bid amount of the last winning bidder is what all winning bidders pay for each item. Note that the bid if for one of the total quantity and any winners must multiply their quantity by the final winning bid to know the amount they owe the seller.

Highlights of this feature:

• Can charge final fees on each items of the quantity sold.
• All winners pay the same lowest winning bid
• Each bidder can bid on the amount of the total quantity they want. If they won they would owe the winning bid times the number of items they won
• Each winning bidder can leave a feedback for the seller. The seller can leave feedback for each winning bidder.
• There is only straight bidding in a dutch auction. There is no proxy bidding.
