Hi! So I want to buy the game within the next week once my 14 day trial is up and I am playing using my PS3. My questions are can I buy the game via the PlayStation network or do I buy the game on the SquareEnix site? Also once the game is purchased then do I buy the subscription fee next? Where do I go to buy that?

A list of what to do and where in order would be great. Thanks for your help.
