Here please first log in to the back office and change to the tab “Profile”. You can then either extend the validity period of an existing card by clicking on the “Edit” button or save a new credit card at “New Creditcard”.
If a current subscription order exists, no further step is required only if the validity is extended, here all changes are now already noted in the system and also for future deliveries.
If you want to select a different payment method when ordering your subscription, click first on “Subscription Order” at the top and then on the “Change” button on the right for “Payment Method”. So you can select the pre-saved new credit card or by ticking the check mark at “Use new payment method” and then “Create New Payment” alternatively also use bank booker or PayPal.
Don’t forget to save your changes in both cases!
