It can be fun as long as you realize what you are in for.
I always warn a seller that I HAVE to try and low ball them, then maybe work my up up to a reasonable price.
I try hard not to pi$$ them off if I have any real intent to buy.
A few years ago I had an OLD snowmobile up for sale.
Decent sled for the $300 I listed it for, but knew I would take a little less to get it gone.
Buyer, his wife, and kids came looked, started it and looked ready to load it on their trailer.
Guy offers $200, I say OK.
His wife goes "$100" is probably best we can do.
I told them for $100 they can stick around and watch me pour gas on it, set it on fire, and burn in the driveway.
She was a bi+ch, so I did not give a $hi+ if they bought any longer or not.
She scowled and could tell she was ready to slap me and gouge my eyes out.
Guy sends her to the truck with his kids and hands me $200 ca$h.
I think I got my point across.
