My mother let me use her credit card, I activated my account to the Full Game instead of the trial. Now that it's activated can I get the card off my account and still hae that 1 month until I go get a came card?
As long as you are still within your first month of service, you can select "Change Subscription" and either leave the information blank, or enter a prepaid gaming card. If you do this within your free month, your Credit Card WILL NOT BE CHARGED. However, you do need to cancel the credit card information on the site, or when the prepaid game card runs out, your credit card WILL be charged.
You will be able to play World of Warcraft as long as you are within your free month, and your account will be accessible and playable until that month is up.
From there, you will need to buy subscription cards ($30 at most gaming stores) that will allot you 2 months of gametime. You enter this information in Account Services the same way you would a credit card (but in a different spot).
You may even get a game subscription card, cancel the credit card charge, and enter the game subscription number to maintain uninterrupted service.
Please understand that you You WILL be charged for the game upgrade, if you did a digital download/online upgrade instead of purchasing discs, but you WILL NOT be charged on the credit card for the game time if you are still within your free month.
If you do not like prepaid game cards, you may also use PayPal or PaymentOne.
