Sometimes it helps if they add a little something to "Sweeten the Pot". I once was hmming and hawing on a 6" 28-2 and the seller didn't want to come down on his price. I can respect a persons "firm" price but figured it wouldn't hurt to ask if he could include a box of ammo from his table (this was when prices were closer to normal). He looked at his supply and said he didn't have any .357 or .38 Special. I pointed to a box of .44 mag and said I did have a 629. He shrugged and handed me the box, and I went home with a nice S-prefix model with diamond target stocks.

I'm not the sharpest knife in the, uh..., place where they keep the knives, but I reckon a seller wants to finish the show with as much money and as little product as possible. This way we both win.
