^ You should also be aware that YesAsia's price might change as the release date gets closer. If the price does change and the price goes up, you might have to make another payment to cover the difference, or if the price goes down, they might credit the difference to your account.
I'm not sure exactly what happens when the price changes, since it's never happened to me, but I do know that YesAsia does adjust their prices from time to time - usually to offset the cost of their "free shipping".
