Yeah! I still remember the rush I got doin' the "refresh rapid fire" during the closing minutes on my White Elephant! I think what hair I had that didn't fall out from stress certainly turned a definite shade of grey.
Congrats on a successful sale, and don't worry, the odds are greatly in your favor that the guy will come through. I know nothing SEEMED to happen fast enough FOR ME when I won the bid on mine, but in reality it all fell nicely into place in quite short order!
