Offer / counter-offer? Audiogon rules

Strike while the iron is hot.

Be patient, you learned. If they come back they "want", to buy it, not forced to buy it.. BIG difference, in a win, win, sale, AY!

One thing I would avoid is dealing with people who want to contact your via "in mail" on the site, then want to negotiate outside of the formal Audiogon "offer" method.

I had a guy who said he had all sorts of questions about the unit I was selling, asked for my phone number, called me, we settled on a price, then when he arrived at my home to pick up the unit, said he thought about it and decided to offer me $600 less.  So I sent him packing.

as others have said, once offer declined, no obligation either direction

I would simply write and ask if they want the piece, and if they still want it for their offered price. 

You could say you realized you were being needlessly rigid.
