What to do with very low offer on an item for sale

@thecarpathian what he said politely is that some of us have class. 

Ignore it or send a note of appreciation but no interest at the price they are willing to bid especially if in excellent/mint condition.  I do this all the time and have sold many pieces over many years.  Also the variable of how long you want to wait to sell the piece has to be considered.  If they want it they will let you know.

Years ago abroad, a few of us were swapping stories of bargaining and my friend David told me of an attempt to buy a rug in a rug shop in Cairo. He offered what he thought was a well-crafted low-ball offer, in hopes of moving to an acceptable place in the middle.

The owner looked startled, grabbed David by his shirt and rushed him to the door and shoved him into the dusty street. He slammed the door shut and flipped the sign to "closed".

We agreed that this was the most spectacular fail at negotiating we could recall.

@timothy468 not even close. 

I got into hifi because my friend decided to go with CDs and sell his turntable. I asked him how much he wanted for it. 

"60!"

"I would pay 70!" - I yelled. 

"OK, 80 and it's yours!"

"done!" 

I wish I were kidding. I keep making similar deals, but at least I whisper

@retiredaudioguy - Ok then, I just learned something. To my recollection, Cross was blue, Golden Cross was a reddish color with grey shrink (later black), and Golden Reference was black with grey shrink (later black).  The ad picture appears to display the reddish color, at least to my eyes.  I didn't realize that GR was ever that color.

If they are in fact Golden Reference, then you should change your ad text since the title says Golden Reference but the text says "A pair of the classic Cardas Golden Cross interconnect.".

BTW, I couldn't get the image link you posted to open up.
