Sony's having a massive sale of all it's goods here in Australia ATM.
They have the Sony VR Helmet + PS4 Camera + one VR game, selling for AUS$100 less than what the VR helmet was costing by itself, so basically 30% off.
I think after the initial pre orders were shipped, the next batch of VR helmets have been sitting in shops gathering dust and they are hoping Grand Turismo Sport might help shift a few units, but from the reviews I've seen it hardly seems worth it, as you can only race against one single car and view the cars in your garage in VR, that's it.
