Quote:

Will there be a monthly fee to play the game?
Yes. After the end of the free month included with the game, you will need a subscription in order to continue playing the game. You have three options, as you will see when you create your account: a month-to-month package at $14.99 per month, a three-month plan at $13.99 per month, or a six-month plan at $12.99 per month. You can also substitute game cards, sold at major game retailers, for the monthly subscription.

Why isn't World of Warcraft free?
World of Warcraft will require a fee to play. This fee will be used to support the costs associated with the high-quality levels of service, support, and ongoing content creation that we are planning for World of Warcraft.

Will there be multiple methods of payment besides just credit cards?
Yes, we plan to support a range of payment methods. In the initial launch regions of North America, Australia, and New Zealand, customers will be able to pay their subscription fees by major credit card, PayPal, and pre-paid game cards. Payment methods in other regions will be announced at a later date.

Note: We are still working with PayPal to allow customers to subscribe using PayPal accounts. Please keep an eye on the main World of Warcraft website for any news on this option once it becomes available.
