Here you will find all the information on how to book by bank transfer or cash deposit: Bank transfer JOYclub.
With a bank transfer you purchase a 6 or 12 month package for Premium Light or Premium. The packages expire automatically after the booked period, so you don't have to cancel. For an extension you can book the package again at any time.
If you want to choose whether you want a 1-, 3-, 6- or 12-month membership, you can buy a subscription.
