It's a combination of things, as others have said. The most common form of low-baller is somebody who offers 60% of your asking price. I have no problem with somebody asking about getting it at 80% of a competitively priced piece if they explain their offer. Usually, when somebody is wanting to give you 85-90% of what you're asking, they explain their reasoning. Low-ballers tend to ask for 60-70% (and sometimes even much lower) and give no context. -Kirk
