Yep -- in my case it was $12.
I've sent the guy another pm and will give him one more chance, if that doesn't work, I'll gladly post his name.
I even sent a copy of the bounced check back to him, and the bill for the $12.
We'll see what happens, his bank confirmed there was enough money to cover the cost in his account now but they can do nothing. He was charged a fee due to his bounced check, they did tell me that much.
