Pathetic, I'm smart enough to know that you don't have a dupe at all. I've seen your partner Countdown scamming on another site and you're here to scam even more.

I see you have Trade with Caution sign, I sent you a PM and asked for a picture proof of your stock. You ignored my private message, I think the other buyers would like to see a picture proof too.
