1. In your dashboard, go to Account Billing → Payment Methods.
  2. Under Card Lists, click Add new card and enter your card details (Visa, MasterCard, or Amex accepted).
  3. Fill in your Billing Address:
    • Street Address
    • City
    • Postal Code
    • Country

Your card is now saved, you can make the new card default and then it will be used for future subscription charges and add-on purchases.
