You can pay by Credit/Debit Card. Payment is generally of a subscription nature so you will be auto-billed every month or year depending on what sort of subscription account you choose to purchase. Your subscription begins from the date that you pay. For example, if you purchased a Monthly Student Account, you will be billed every 30 days from the day that you purchase until you decide to cancel your subscription. You can cancel your subscription very easily – see above “Can I easily cancel my subscription auto-billing?”.
