The game comes with a skateboard peripheral and can't be sold solus so I'm guessing this is a mis-price!
It's a win-win situation as if it turns out to be solus you can cancel your order and you won't be charged!
You won't even be charged until the game is released which is October, however, if this is a misprice then they'll have to honour and for the game plus the peripheral at this price is an absolute steal!
Get it before they rectify the price!
I will repeat you can't loose out as you won't be charged until the game is released so if a seperate bundle copy does appear you can cancel your order and won't have been charged!
