so i'm going to pre order FIFA 17 from the store. But I'm not sure how the process of pre ordering a game works. Do I have to pay the whole price of the game or just a a porcentage of it?
On the PS Store, the full amount is typically collected upfront and you are unable to get a refund, except for in states where required by law.
In most instances you pay for your pre-order when you place it and this is made clear during checkout. For a few products (mostly PlayStation VR titles) we will not debit your wallet until a few days before release. This will also be made clear at checkout. In addition, we will email you once you checkout to confirm the details of your pre-order and whether we have taken payment immediately or will debit your wallet nearer the release date.
