iTunes: These payment options are available

You don't necessarily need a credit card to buy music, movies, or books on iTunes. You can read about the other payment options available to you in this article.

With these payment methods you buy on iTunes

• Credit Card: Apple prefers to pay with Visa or Mastercard. Another option is to pay with an American Express Card. But it works even without a credit card:
• Clickandbuy: This is a subsidiary of Telekom, with which you have to register. You deposit your bank details with the Clickandbuy service, which then pays for you on iTunes and later debits the money from your account.
• "None": If you select "None", you can redeem iTunes gift cards. You can get them in all major supermarkets and electrical stores as well as at petrol stations.

Incidentally, you can easily cancel your iTunes purchase and then usually get the money refunded immediately. More info can be found here.
