We only use PayPal for course payments. But, you don't have to have a PayPal account. With PayPal you have the option to use a standard credit card at the time of payment. Don't let the lack of a PayPal account keep you from signing up. Just click the payment button and look for the small wording that says something like "Don't have a PayPal account? Click here."
