In a move that no one is very clear about at the time of this writing, Apple has eliminated the possibility of paying by bank transfer in the Apple Store in Germany. Right now, the payment options in the German online Apple Store are by credit card, PayPal or by means of financing that will allow users to pay in installments to be able to face the payment.
It is not clear if this option has also disappeared from Apple Stores in other countries. What we can assure you is that in Spain it is not, offering the payment methods of credit card, gift card and through financing, but personally i'm not sure if the option was previously unavailable. Until a few hours ago, at least German users could pay by making a bank transfer instead of having to use a credit card.
It is no longer possible to pay at the German Apple Store by bank transfer
The UK bank transfer support page shows information explaining that users residing in the British Isles must call a specific phone number in order to order. On the other hand, the same page in Germany still available, but the option has disappeared at the time of payment Of the order.
Without official information, the only thing we can do is speculate on the reasons why the Cupertino people have decided to eliminate this payment method in Germany. One reason could have something to do with Apple Pay, more specifically in Apple Pay on the web, a payment system that we can compare to PayPal. Most likely, we will find out all the details of this move in the next few hours.
