Is swedechris (Chris Osterberg) in Sweden?
International buyers tend to flake more, especially when you tell them the shipping is in the $30-$35 range! Yip, this person has done the same thing to me...asking me for pics and saying he's going to buy and then disappearing.
From experience, cash is king and first come first serve. So when I sell something, whoever pays first gets it. I don't care if I promise the 1st potential buyer I'll hold it for them. If the 2nd buyer pays first, then the 2nd buyer gets it. That way, I don't care if the 1st buyer flakes or not (many times they do flake).
