Subscriptions will automatically recur at your chosen rate (monthly, every three months, or every six months) using your preferred method of payment until canceled. You can cancel your subscription at any time.
When using a credit card for the first time, your credit card or bank statement will show two charges for the same order. However, you will pay only once. The first charge is called authorization hold and is a common banking practice. The authorization hold is automatically refunded within 2-3 business days. Only your financial institution can remove an authorization hold.
To view your subscription history, visit your Account Management Transaction History page.
Prepaid Game Card
If you want to play without a recurring subscription, you can add prepaid cards to your account. If you later add a subscription, you will not be billed until your current prepaid time runs out.
Game cards must match the region of your World of Warcraft account. In addition, game cards must be activated by the seller at the register.
Note: Your card might actually be for Battle.net Balance, not Game Time. If claiming the card does not grant Game Time check your Balance, which you can then use to buy digital game time.
Digital Game Time
Digital game time can be purchased in the Battle.net Shop and works similarly to prepaid game cards — payment is not recurring.
Digital game time can also be gifted. When you buy digital game time as a gift, a code will be sent to the recipient's email once your order is complete.
It is not possible to pay a recurring subscription with Battle.net Balance, but you can use Balance to buy digital game time.
