Thanks Paul. I paid online and then printed the form to show gradient etc. I put the order number on the printed form so it all matches up. What is worrying me is that the stupid lady at the post office hard sold a 4 day delivery service to me. It needs a signature at the other end. Im worried that it will come back as I bet there is no one at the PO Box to sign for it. Arrrgghh! :-s
