Retract offer

nickcaper- offers not accepted within 48 hours are automatically cancelled.  So it's 2 days, not 30. 

I disagree with a lot of this thread. (2) days is too much time to consider an offer. As a seller, You know how much you want for an item so you have the decency to either accept, counter or decline. This gives the buyer the opportunity to up his offer, make the purchase or move on.

It is real simple. There should be a 24 hour rule for buyer or seller to decline. I love Audiogon but I am not going to sit around and wait and he seller has declined my offer twice so I moved on then they accepted an offer after I already found a deal on another pair of speakers.
I am not buying both speakers.

...Should the seller be at a loss if another offer is lost because the first pending one is lost? These deals can have a domino effect. One could make an offer with a time limit at the time of the offer.
