If Audiogon would just charge a flat fee up front it would not matter how we communicated between buyer and seller. If they wanted more money for high dollar items they could just charge more for those.
If they persist with the model they have now they are going to fold. It has become too risky to do business there now. Why pay their fees when they really don't offer any more protection from fraud than Craigslist.
Very good points!
Or maybe some sort of membership fee that could somehow be offset against selling prices to weed out the hackers?
