You can register for our free customer club called "Club Zizzi" on our webpage. You can find the registration form at the very bottom of the homepage or by clicking the human-icon in the upper right corner of the window and clicking Create Account.
When you sign up for our Customer Club, you will receive a welcome e-mail containing a link to generate a password for your new account. Only when this step has been completed, your registration is successful, and you will receive your welcome voucher in a separate e-mail.
