o.k so the moral of all the people who have expressed themselves here is that if u are first time seller, u be the scrapegoat.
Geez, could you be any more melodramatic? It's nothing personal on our part, just good business sense. Look, you have two options here: either (1) hold out until someone agrees to pay first, or (2) ship first to someone with plenty of heat (it may not be a 100% safe strategy but it's as close as you'll get when it comes to internet trading). Either way I don't see what the big problem is, and why you feel the need to complain about it. Just make your decision and stick to it.
If it makes you feel any better, I'm hardly a newb anymore but as a gesture of respect I still offer to ship first to those with significantly more heat than me, and I have yet to be screwed over by any established trader here at AT. In fact, the only troll I *have* run across was a newb just like you. So you wonder why established traders don't pay first? That's why--thieves have ruined it for all of us.
