If you choose to checkout and pay via PayPal, you will be redirected to PayPal at the end of the order process.
If you are already a PayPal customer, you can log in there with your user data and make the payment. If you are not yet a PayPal customer, you can log in as a guest or open a PayPal account to make the payment.
The receipt of payment is usually booked within a few minutes and your order will be processed immediately.
