We try to authorise payment for your order the day before or on the day your order is due. Occasionally we're not able to get a successful authorisation message from your bank - this can happen for several reasons. Your bank will be able to provide you with information to explain why this has happened.
We can't fulfil orders without successful authorisation, so we will need to cancel your order. If this happens, we will notify you via email before your time slot, and a message will appear on your Order Details page.
For more information on how we take payment, please see Charges, authorisations, and payment.
