According to the end date in the original post, this auction ended on Tuesday. A "superduper magixd sexilicous deal" is not a valid way to end an auction. According to later posts, the original poster ended the auction after DarkHunt had made the last legal bid.
Also, no, accepting CD keys as payment for an item is not allowed, for future reference.
Therefore, this auction was won by DarkHunt, since dentian's bid was made after the ending time limit.
