In case you encounter any errors upon checkout when using your PayPal as your payment, please know that the most common reason for the error is that your shipping and(or) billing address saved in your PayPal account has some kind of problem. The billing and the shipping address might be different from one another which might have triggered the error to happen. Please contact PayPal and ask for further assistance. Though, if you are sure that everything is working out with your PayPal account, then please get in touch with us and we’ll assist you.
