If you buy this item postage should be added automatically to your bill. There is a standard postage charge as it is all this website system will accept. If you have paid too much we will refund you on shipping to the nearest pound.If you have paid too little shipping we will pay the difference within reason. If the website chooses to be in a bad mood, as they often do and doesn't add shipping/postage costs, you will be invoiced for the actual cost when we have it. We aim to post within 48 hours max.
