For making the payment for you as convenient and safe as possible we are offering the payment via PayPal (a service used by several million people, mostly on eBay).

If you do not want to use PayPal and prefer a bank transfer you may also request our account information.


The payment is arranged via PayPal. This service is taking care of the whole payment process. The following payment methods are offered:

  • Bank transfer
  • Credit cards

The payment process is running on a SSL server. This means that the data stream is encrypted to assure high security.

You will receive your registration code at the latest 48 h after we will have received your payment.
