If the authorisation fails, the most likely explanation is that you have input your card details incorrectly. If this happens, press the back button on your browser and you will be returned to the card input page. Check that all the details are correct, and make any changes necessary before proceeding.

If all the details are correct and you still fail to get an authorisation then we advise that you contact your card issuer to establish why your card was not authorised. We will receive your order anyway and may contact you to arrange for alternative methods of payment.
