Is a offer of -20 percent on an OBO ad insulting?

Whenever you place an ad to sell an item you should not be suprised when you receive low offers. A simple courtesy e-mail is all the response that is required. I have sold a couple of houses thru realators as well as one on my own and received offers that I considered low. These offers required formal responses by me which took significantly more time than an e-mail. The people making the offer maybe doing so for various reason. However, as one person above stated; this is business and as such we need to understand that and not take it personnel.

What is OBO except an invitation for low offers? An offer of 80% of full price does not deserve rudeness. The buyer may well have gone to 90% or even 100% with a little bargaining.

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

i think it depends on the selling price. if the selling price is low then 20% is too much. i look @ things a little differently. we are a small group of people that "do" this hobby. if you are "doing" the hobby then you know what is a fair price and what is not. to take advantage of someone because they are in a bad spot is not honorable. i would not like someone to take advantage of me if i were in a "pickle". its not all about money. if the person cant afford it then they need to save the money. gee what a concept.

20% is probably not terribly unreasonable. Being a seller myself, I can understand the sellers point of view here. It's exteremely irritating to get many low ball offers in a row. For example, I had speakers listed at 825 for the pair plus shipping. Someone wrote me and said they would give me 500 shipped to their area. I noticed a lot of people don't do research before they make offers. Look at other units similar to what you want and see what they are going for. Then consider an offer.
