You may choose either a Auction or an Instant Purchase. You may select for Dutch auction or Dutch Instant Purchase as well. A Dutch auction or Instant Purchase is one in which you have several identical items to auction off, and is more convenient than entering your items as several separate auctions. If your quantity is 1 or if you'll be selling to only one bidder leave the 1 in the box. If you are selling more than one of the same item, change number in Dutch Auction to quantity you have.
