I’ve entered the product key for the expansion upgrade and it asks for billing information and to choose a subscription. Isn’t DDO free to play? Am I going to be billed for a new VIP subscription if I upgrade?
Dungeons and Dragons Online is free to play. If you upgrade your account and have an existing VIP subscription, you will not be billed until the end of your current subscription period with whatever subscription plan you chose when upgrading. If you do not want to have a reoccurring VIP subscription, you can choose the payment type “Game Card Or Other Payment Methods”, and click the box that says “I don't have one right now, I will enter one later”. This will prevent your account from being billed for a subscription payment, or if you are currently active as a VIP it will prevent your subscription from automatically billing unless you chose to reactivate it later.
