There are two types of subscriptions available:

Gift Subscriptions are one month subscriptions you can purchase for yourself or for another player. Once the month is over, you will lose all perks gained from the package. These subscriptions do not auto-renew, therefore credit card information is not required - perfect for those buying with a PayPal balance or if you've received a voucher code.

Recurring Subscriptions are subscriptions that will auto-renew each month. You must have a credit or debit card to purchase a recurring subscription. You can use a voucher with these subscriptions but it will only apply to the first payment.
