A. This simply means this product is not currently an item we keep in stock. But, is usually available from our supplier within 5-7 working days of your order being placed. Whilst we will pre-authorise your credit or debit card at the point of ordering, no payment will be taken for this item until we have contacted you to confirm that we are in a position to despatch the product.
