sometimes people are away from their PC or whatever and don't get the memo on offers. the time limit is a bit of a drag too, 48hrs is pretty short as time frames may go, but I guess the cut off has to be somewhere.
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?
