With this system you can buy un-used (inactive) characters by auctioning for them. When you bid on a character it will automatically take premium points from your account. If someone out-bids you, you will get those premium points added back to your account. If the auction time is under 2 minutes when someone bids, 1 minute will automatically be added to the auction time to give time for a re-bid from the previous bidder. If you choose to "buy now" you will get the character within 1 minute.
