They are free if you got in on the IGN thing. Or $15 if you got in on the Target deal last year.
Yes, they get deleted when it expires, but I'm sorry to kill the circle jerk, but nobody fucking cares about a physical copy except fetishistic forum gamers. It's 2012. If you need a cloth map and pendant for Uncharted in order to make it feel special, you can make them yourself out of paper plates, macaroni, and glitter.
