Item Market
Game Menu -> Market -> Item Market

On the item market you can sell your items via Auctions. You can sell any type of item here. To add an item to the market, you have to go to your Item Inventory and select the item and amount as well as the auction duration. You can only have 5 items on the market at the time. An auction cannot be cancelled and the system will take 3% fees from the winning bid (if big enough). If an auction is unsuccessful the item will go back to your inventory if there is enough space.

Anytime you bid for an item, the bid will be taken from you temporarily and the previous bidder gets his bid back. If nobody else outbids you until the end of the auction, you will receive the item and your bid goes to the auction host. If you bid right before the end of an auction, the auction duration will be extended.

You can also watch any auctions by adding them to your auction watchlist under Market -> Item Market Watch. Finished auctions will go to your auction history under Market -> Item Market History.
