Are you getting ridiculous offers from new members

I thought the same thing dill...

"Yea, he might be flipping it on eBay or another site, not surprised he asked for more."

I honestly hadn't thought of that.  Well, at least nobody died (as far as I know, anyway).

I have never sold anything here, but I found out most of the time the asking price for a demo with factory warranty is cheaper than that from a private seller. For example, Pass Labs XA30.8 from a dealer in Nevada.

  you know, sometimes sellers ask a very high price.  If nobody is buying at your price then maybe that dosn't mean that a lower offer is a lowball offer.

I think that's just the nature of dealing with the public.  Back in the late 70's when I sold high-end equipment at a brick-and-mortar retail shop, same sort of thing would happen back then.
The worst Audiogon experience of this type was when a guy who lived about an hour's drive from my home said he insisted to pay me cash, we talked and came to an agreement on the price, when he arrived at my home he said he thought about it and changed his "offer" reducing it by $600.  My takeaway from that was that he was attempting to circumvent the process of making a formal offer on Audiogon, so there would be no evidence, so when someone uses the Audiogon email system to negotiate the price, I make them make a formal offer.  Using that method, I still get the "low ballers", but haven't had a real sale that wouldn't go thru.
