We do not routinely use 'inventory control' on our website. We understand our customers' ordering habits and maintain sufficient stock to cover the majority of orders immediately. If we receive an order for a product that has just gone out of stock we will contact you to advise of any likely delay. If you or your company wishes to place a particularly large/wholesale order it is sensible to speak to us by telephone beforehand so we can advise stock levels, any additional discount that may apply and an anticipated completion date for your order. If your order exceeds our normal range for value or weight, the site will not permit you to select a delivery method. If this happens you can still complete your order and we will contact you with details of appropriate shipping options and costs.
