I just submitted my payment request. Can I change my PayPal email address or select a different method of payment?

Yes, probably. When you requested payment, we automatically sent you an email letting you know that we'd soon be sending your payment. That email contained a link that allows you to cancel your payment request. Click that link to cancel the payment request. Then visit Account Settings to update your preferred payment method. You can then request payment again. Note: if we have already processed your payment request by the time you click the Cancel link, it is too late, and we cannot change the payment destination.
