Autobuy has been reached. Sell it to the guy who 'autobought' it. It is an auction, as long as the guy has the tc to pay, you can't really disregard him.
Closing the thread. If, by any chance, he doesn't want the head anymore and you prove it to me by screenshot of a PM, I'll reopen it and let you change the autobuy.
Edit: If I see you doing something else, like selling it to someone outside of this thread, I'll slap you with a ban.
