This means the item is out of stock but available to order by clicking on the button. An estimated delivery time will be shown next to the item but it is subject to the manufacturer having stock and sending it to us. Due to the indefinite delivery schedule of back-ordered items we are unable to accept pre-payment for Available to Order items. You may still order these items by providing a valid credit card number and details and keep us updated with any changes. Your credit card account will not be charged until the item is ready for despatch to you. Back ordered items will be shipped at the price prevailing at the time of shipment. Note however that cancelled back orders may be subject to a cancellation fee.
