If you submitted the work and paid successfully but want to upload your work one more time because it has an error in it, here is what you can do: upload the work and when you are taken to the PayPal webpage and asked to pay just close your browser. Do not hit your ‘back button’ just close your browser at the Paypal page.
Paypal allows you to pay by credit card within their system – you do not need to have a Paypal account to do this. Proceed to ‘Add to Cart’ and follow the credit card payment steps. You do not need a paypal account to do this. (Note: If paying by credit card choose the dropdown default shipping method when you get to that field)
