Offer / counter-offer? Audiogon rules

Legally, at least in the US, the answer is no. Once you counter, that is an implied rejection of the original offer. Full stop.  I can find the UCC cite.

If the customer walks what do you have then?  0 + 0 = 0.  Great time to add to the sale and increase your revenues when you get them to part with their money rather than sitting on your inventory.  There is something called the cost of money.  People want to walk out thinking they got a deal.  The same applies to when you purchase a car.  How many consumers walk out of car dealership paying full list price?  So, why should selling audio gear be any different.

I receive real estate listings from a realtor and have yet to see a pair of speakers in a room.  So this means how many people actually buy audio gear in the first place?  What are dealers then doing to educate people and to create interest?  i have yet to see a TV commercial from a audio dealer other than TV's.  This is why you see $5,000 entertainment furniture with a wide screen TV and no speakers when sound is probably 70% of the experience.

I like the system as it is set up with the counter offer in place, with that said I made an offer on a turntable, a brand I wanted to try, that was 10% lower than the asking price which the seller declined and I moved on, about 3 weeks later he reached out and asked if I was still interested and I purchased it for my original offer. The seller was a member in good standing and I left him his positive feedback but he never left mine for me, just chalked it up to maybe he was a little upset at not getting his asking price, but who knows. I also use the counter offer system to great effect when selling here and on the other sites. Enjoy the music

I have found that if I state that "This is my only offer, please no counter offers"  I can let the person know what my thoughts are ??  

The current system works. Unless of course you counter an offer you wish you hadn't.
