I say: take your time. There are gonna be plenty of deals on kingsnake.com.
If it is a scam, I'd hate to see you get scammed.
Most of my snakes have come off of kingsnake.com. I did get shafted once by a breeder sending me a sick snake, which later died. He said one of his employees pulled the wrong tub. BLAH, I'm not going to ruin my day writing about that situation.
All other transactions on kingsnake.com have been a pleasure.
The only way I'd send a check or money order is if the guy was a well known breeder, etc.. I've sent a check on 2 occasions to reputable folks and the experience was great.
Be careful and take your time!
