PS3 owners who haven't yet got themselves GTA IV might find this offer to good to refuse.
GAME are right now offering the Grand Theft Auto IV Special Edition - which you may recall includes "a fancy metal safety deposit box, The Art of Grand Theft Auto IV hardbound book, a selection of music tracks and limited embossed cover art" - for just $49. Typically you'd pay $69 for the standard edition.
The GAME offer is online-only and only for the PS3 version. Sorry PC and 360 owners. And I imagine it won't last long.
