When using PayPal, please remember that PayPal has very high security standards. Any incorrect name, address, phone or credit card information can block payment completion for your registration.
You can indeed use PayPal without an account. Once you click through the EventBrite course registration page to PayPal’s 1st payment page, you can click on the Continue button at the bottom left of the page, highlighted below to pay without an account from PayPal. You can’t use your old e-mail address or credit card that is registered with PayPal if you use the “no login” method.
If you continue to have issues, please contact PayPal or your bank for authorization issues or Freakalytics at “Billing” + “the @ symbol” + “Freakalytics.com” without the quotes for other issues.
