Some folks have an overinflated value of their gear coupled with a fragile ego. After the items sits unsold for a while, reality sets and they take what they can get.
Ignored Offers
I have been buying and selling equipment on this site for many years. I have noticed recently that sellers are ignoring my offers. In one case my offer was more than the item eventually sold for, so clearly it was not a low ball offer. The other item I bid an amount based on prior Audiogon sales. Any one else notice this trend?
