What courtesy? It's been TWELVE DAYS.
I'm just as busy as the next guy, own my business, literally go days without sleep and no time to get on a computer. On the weekend I'm in the boonies with no computer. But if I am selling something, or put myself in the position of having to reply to PMs or e-mails, or phone, I get back within a few days.
I sure don't blow someone off just because an item is sold.
And I have sold items on other boards. So I do know how it is.
On the other hand, there is always the legitimate out of, sickness, death, family emergency, etc.
Any of which would make me feel 1 foot tall right about now.
