Why was my payment declined? If you are having trouble paying with a credit or debit card, declined payments may be due to one or more of the following:
PayPal: - The transaction page has timed out.- Exit the page before completing the check-out procedure.- Your PayPal account does not have sufficient funds or is not linked to a secondary option such as a bank account or credit card. Please contact PayPal for detailed questions about your PayPal account.
