Is it my imagination?

I agree with the points made, and support the mechanism of the free market. On the other hand it misleads buyers who make offers in good faith and are either mucked about while the auction concludes, or stood up when the eBay bid price closes the margin. Personally I would post feedback if I believed I was misled in this way, simply to let others know that they should be aware of the seller's lack of authenticity. Free markets operate better with better information.

Coltrane1, you are missing the point that people are advertising stuff for sale on Audiogon that they do not own, and are merely a bidder on at Ebay (and other variations). There is indeed nothing wrong with buying and selling stuff. It's a free world but serious buyers are often jerked around here by a seller that may or may not have the item to sell.
