Thank you for the suggestion. I am not BSing anyone and I will gladly post proof of the offer. Here is a link to the offer screenshot, with the sender´s info censored : http://imgur.com/a/o6I0e

With the escrow however, I will not transfer ownership as the winner might not be willing to pay escrow fees - see rules in the initial post.
I have no problem with escrow, but winner would have to pay any expenses associated with that
