Apparently not always. A game was recently offered for sale here, and I responded to the seller that I would buy it, sight unseen, for his asking price. He said he would hold it for me until Sunday when I could come and pick it up.
Well, as is usually the case, the more time that is allowed to elapse between a verbal agreement and when a game is actually loaded into your vehicle, the chances of "something happening" increase exponentially with each passing hour. In this case, the seller's wife somehow accidently sold the game. I don't know about any of you guys, but there's no way in hell that my wife could ever sell one of my games without me knowing about it! OK, fine. Someone obviously showed up, cash in hand (maybe more than the asking price), and bought the game. It happens. Like I said, until a game is in your vehicle and that vehicle is moving toward your house, anything is likely to happen.
No biggie. I don't really need the game. I was going to help out a friend who has this game with a rough playfield, then sell the remaining game for whatever. It just sucks when this type of thing happens even though it seems to happen all the time now. Move on.
