First one I don't think has much value. (Sorry If I am missing important meaning of it) The epeeds one maybe $xx to Mid $xx And the last one is a keep one. You can get around Mid $xxx to High $xxx for it from the end user.
why you buy d-d2.com since there are a lot of other 4 character without dash still available for register? it can be read as : The Diablo II you can sell it to diablo2 battle.net player
