Antiques Dealer: How do I use the Auctions?

The Antiques Dealer also offers you the opportunity to win some exciting items, as well as some which are exclusive, by bidding in his auction. Bids can be made with Trade Coins only, and you're bidding against other players! If you're outbid, your Trade Coins will be returned to your stock for you to spend on another bid, or other items if you decide the price is too high. The player with the highest bid at the end of the auction wins the item. Also, if you bid within the last 30 seconds of an auction, the timer will reset to 30 seconds, giving others the opportunity to make the Dealer a better offer, so make sure you stick around until the last second if you want to ensure you're the winner!
