*** Update: October 10, 2020: The issues have been resolved, and credit card payments are possible again! ***
This morning (Friday, October 9th) we received news that there are currently massive problems with payments via credit card through the payment provider Stripe.
What this means for you: We are enabling payment via Stripe. Currently, you can only place your order via PayPal or bank transfer. Payments via PayPal with a credit card are not affected!
We apologize for the inconvenience. We'll let you know here as soon as the issues are resolved!
