20% under is not an insult. I listed some speakers a long time ago and got offers at 50-60% with "advice" that I was way overpriced. Those were insults. I kept the speakers, sold them years later for little less than I had paid for them, and recently saw them on Ebay (yes I recognized them from the picture and serial number) for even more. I listed a sub and got offers 20% under, those were not insults. But I kept and still use the sub in my second system. An insult is an insult. 20% under if the seller says "obo" is not an insult
