Cash On Glass !!
What don't you people get about this ?
Buy local, go kick the tires, if you like it, don't argue the price, buy it and be happy you found a cool game.
Bring a friend, take a truck or rent one, bring a dolly, and straps.
Thank the seller, be nice, who knows what they might sell in the future. You might meet a new Pinball friend.
Six of my games came from Pinball/Arcade friends I've met in the last 11 years in the hobby, who called me out of the blue with a game for sale.

Easy Peasy.
