Yes, that is correct. From now until October 2nd (or until they’re sold out) you can purchase the Playstation Move Motion Controller, Navigation Controller, Charging Station or the Move Sharpshooter for up to 50% off from GameStop. Or you can just purchase them all together for about $75 (excluding shipping).
Maybe you already own everything Move, if you just so happen to be short on games, GameStop is also discounting a selection of Playstation Move titles to $9.99. Head on over there while supplies last!
