I found a $10 copy of Shenmue II on Xbox, as well as an N64 microphone/Hey You Pikachu! for $10.
The Shenmue II has one of those "Microsoft Company Store Purchase" stickers on it, and still has the seal on the side of the case. The shrink wrap on it wasn't original, the store I bought it from put on their price tags and then sealed it. Is this worth anything? Was this just what you got if you ordered a game from Microsoft or was it something only employees in Redmond could buy?
