Since this guy didn't have any feedback, I'll make the thread for him...
He posted in my thread to buy my friend's dm4. Talked to him for a while, and he seemed pretty legit.
He wanted me to hold it until the weekend so he could mail the Money Order. I was a little apprehensive, but figured I'd help him out.
I passed on two offers in the meantime, and then have to PM him to see what's going on. I get a reply to the effect of "someone ended up in jail, and I had to bail em out. Can't buy it."
So I'm out those possible sales, based on an empty promise by this guy.
This is just my normal policy. I leave negative feedback for people who ask me to hold something on the promise they WILL buy. Since he didn't have a feedback thread already, I've made this.
