Can I use another person's credit card to purchase a Premium Membership?
While deviantART users are more than welcome to purchase a Premium Membership with another person's credit card, you MUST have the permission of the credit card holder to do so.
Any unauthorized purchases made from a deviantART account will be treated as credit card fraud and the account responsible for the transaction will be banned without question.
In other words, if you are going to use your parents',friends',relatives, etc credit card, make sure they know the charge is coming so that they do not dispute the charge.
Unauthorized usage of another person's credit card is illegal, immoral, and just plain wrong.
