I know it can happen at any time but I've probably conducted dozens of buy/sell/give/receive transactions over the past few years without a hint of trouble. A few times I've had members give me stuff and I've had to almost force them to let me take care of the shipping. Also when I'm making a deal I tend to give members a pretty fair shake as far as price. In a way I guess it's payback for the knowledge I've gleaned from here.
