24hour deal, ends in 12hours at time of posting. Pretty decent deal considering EBGames sell these for $49. RRP is $59.
The 'for Windows' part means it comes with the USB dongle for wirelessly connecting to a PC.
The Xbox 360 controller is considered the defacto controller for PC's. If a game supports a controller, this is the controller it supports.
Good deal, postage is a bit of a killer though.
Postage to Perth is $11.55
