I don't even understand why you'd get your panties up in a bunch over a lowballer; reply if you want, forget it if you don't; if you were buying, you would want to get the best deal you could as well. THey mostly do it due to the fact that some people will be desperate to sell, or just get rid of it for whatever, and some won't. For the record, I typically pay what the asking price is, or haggle a bit off, but there are many sellers who think their shit is worth far more than it actually is.
