Even I am going to try it now..not sure if it will work on not..but I am sure its worth a try..as for the offer that warbux had got, I am sure it was not a very interested buyer..someone who is interested in your domain would at least try to counter your counter offer..which did not happen in this case..so what you did was right..I too have come across a lot of people who just try bidding just so that they can get lucky if someone is foolish enough to sell..
