Why do so many sellers take offense to offers on their listings?

my favorite tim_p was when selling a heavy pair of mid sized speakers,without boxes,  local sale only, "how much to ship to Paris?"...

"I just believe a seller should come back with a reply of what they would be willing to accept"

IME, replying to a lowball offer has never resulted in a sale, ever. 

"If the price is firm don't leave the offer option available"

I use the "Offer" feature so I can check out the buyer. You can't do that with "Buy it now"

@jond i am pondering your generous offer, i can get back to you with my counter in a decade or so. Look for an email from getoffmylawngrouchyaudiophile.org

Thanks for making my Dad’s day……

@markpao hmmm. I think you are wrong. I have made numerous deals and I have made low offers that were sweetened as we negotiated. Not to mention a ‘no response’ makes me hesitant to go after other items a person has for sale. There is one dealer in particular that lists items over and over again. After no response 

from him a couple times I have written him off completely. 

When selling an item here on Audiogon and I make a counteroffer to a potential buyer, am I obligated to sell it to him even though I may have received a better offer while waiting for his reply?
