Boy, this is a tough subject! Very touchy and very grey!
I probably would not have replied at all, except that I can speak from my own personal experience, FWIW.
I have been an eBayer for 15+ years and while I have had my share of close calls, including one rather ugly incident -I have never been left "high and dry."
I have had several transactions here (no idea how many) and I have sent and received gear from all around the world -sometimes for money, often for free or as I like to say: pro bono BeoWorld! I must admit, unfortunately, that I had two transactions that went belly-up and I was basically, as the thread word states: screwed. I am out about ~$300.00USD not including shipping, etc... I tried and tried outside of BW to resolve it, but nothing.
Money is money, they are still printing it. Gear is gear, there is still plenty of it out there! What can't be reclaimed, particularly in one of my deals, was the countless hours of advice, planning, and testing that went into it. But even that "is that." The most important thing lost is the trust -a sense of violation, a rather simple thing!
To my point... Yes, BW has the private sales/wanted section. One would think (hope) that by being a minimum silver member, one would have a vested interest in advancing the reputation of the site. However, this is not eBay and there really is no policing -and one would hope there wouldn't need to be any! But, there is no feedback. No way of saying: YEAH/NAY. It is what it is, I suppose... another tool at our fingertips, to be used at will -but you are on your own. I am not sure what the best answer is. Another forum I frequent, has a secondary numeric count (akin to a post count) that manifests only when in their sales/wanted section. Clicking the number -sends you to the user's feedback. This may be overkill, but as we are about to go into BETA testing on the new site this weekend -perhaps it is something to look into?
I certainly appreciate the sales/wanted here -it has reaped many more benefits than just the outright sale on the good occassions! I would open my home to any of my "friends" and I am confident, as I would travel from Greece, to China, to Australia, or even Kentucky -that an open door and a wet whisky would be awaiting my arrival.
It is very gracious of Lee stepping in here when I don't think he really has to -but I suppose that is what we all expected from the original deal's second party in the first place! Good man! It furthers my belief that this is a great site with a thoughtful, caring, and forthright membership. I sincerely hope the OP and the others can settle all of their disputes... and moving forward -we could come up, collectively, with a way of dealing with this type of an ugly issue that is not just befitting, but can make this an even greater site.
