You can redeem the booked multiple tickets when booking the course. They are offered in the booking portal if you are logged into the website as a member. In the member area you can also see how many classes are still on your card. Unfortunately, multiple tickets can currently only be paid for online via PayPal. If you would like to transfer the amount, write it in the contact or by email, then we can book you a multiple card manually with which you can then book the courses.
