When you go to pay your tuition for your SU online courses, the PayPal popup window should give you two options to pay:
1) Pay with PayPal by logging into your PayPal account, and
2) Pay with a Debit or Credit Card.
To see the second option, scroll down to the bottom of the popup window. Here you will see a button for this second option (see image below). Click it and you will be taken to a page where you can fill in your payment information.
If you don’t see the button, your computer is probably already logged into a PayPal account. Look for the small “Not you?” link towards the top of the page (see the image below). Clicking this link will take you back to the screen above where you can opt to pay with a debit/credit card.
