Sometimes an event offers PayPal as a payment option but you may not have (or want) a PayPal account. If this is the case then you can still proceed with payment via Credit or Debit.
To do this just select the PayPal icon and it will open a window asking you to log in. Instead of logging in or signing up you can select the grey "Pay with Debit or Credit Card" button.
This will open the Guest Checkout where you can input your card information.
After entering your payment information just click the "Pay Now" button to complete,
After submitting be sure to wait until you get to the order confirmation page before navigating away or closing your browser!
