Anyone else receive low offers right away ?

Well I feel left out. No one sends me low ball offers. What am I doing wrong? I have had a few OUS offers for US only sales, but I responded politely with an explanation and found the people to be legit. I still don't sell OUS. Its just too much of a haste. I will buy from Canada if its a rare piece.
The one that really got me was a fellow who accused me of trying to rip him off after we had some confusion over who paid for shipping. At his request, I released him from the sale. Two days later, he made another offer. No thanks.

It is a waste of time . Those who are in support of this probably do it themselves which is fine. You do not have to actually be interested in owning something i am selling but you will not be profiting off me . I need the profits just as much as the reseller who wastes my time with lowballs .And i assume everybody wants to get fair market value . Oh sure you can get steals on CL time from time . I would not equate that into market value .

It is a waste of time

I'm certainly not defending their activity, but I would disagree that it is a waste of time. Obviously it is not or you would not be receiving these offers. I see it as another sign of the struggling economy. Some people will do anything to make a buck these days. I've had a large increase in door-to-door salesfolk in the last year or two as well. There are few real jobs out there any more, as more and more folks are fighting for table scraps.
It's sad, but it is what it is.

So what is a "lowball" really? If I offer you 200 bucks for your amp and the market reasonably indicates it's worth the $1K you are asking, that's one thing. It is quite another if I offer you 800 bucks, especially if the market indicates your asking price is a little on the high side. Maybe I just want to pay "market" or perhaps I want to negotiate something more reasonable. That doesn't make me a lowballer. While I'm sure that some buyers make ridiculous "offers", I'm also convinced that some sellers set prices which are unrealistic, invite offers and then become offended when an offer is made. The simple solution for sellers has already been mentioned...set a price and and put a 'buy it now' on the item. If you are not able or prepared to negotiate price, don't invite offers. Merry Christmas and cheers to all from Colorado.

Just ignore it ... what's the big deal and why take it personally? Everybody wants a STEAL. If they are serious, they will offer again or initate a conversation.

Several buyers ask why no counter when I never thought their initial offer was serious. Gave a FIRM counter and some accept it.
