Summary: Does exactly as described, and the cool part is that when you redeem it, it adds the time like you have been a subscriber that long. For example, if there are 60 day rewards and you haven't been a member that long, as soon as you redeem this code it adds that 60 days to your account and recognizes you as a member for that long, giving you the rewards instantly instead of actually waiting until day 60 as a member.
Summary: Great Price! Almost $5 less than Best Buy and $20 less than GameStop! The code in the box gives you a 30 day trial subscription but you'll need to pay for a monthly subscription after that. Square-Enix has great incentives to keep you subscribed. There are veteran subscription rewards for pay periods which become instant when you pay with subscription cards.
