If you have received an e-mail from us notifying you that additional shipping charges are due, this is where you enter that amount and process the charge.
This process is necessary because of recent changes by the credit card processors to maintain the highest possible level of security for all of our customers. Only the bank sees your card number and we can only issue a credit, never an additional charge unless you authorize it here.
