Shipping games always makes people nervous, as it should. You're basically trusting the other person to describe the game accurately and honestly and to ship you what you've seen. At any rate, one thing I've seen other folks do is post where the game is and then ask if any collectors in the area would be willing to go look at the game and make sure nothing obvious is wrong with the game. While that's not a guarantee that the game will arrive in the same condition as it was when it was inspected, it may give you a bit of confidence that the game is worth shipping and isn't a total lemon.
