Unscheduled delivery means it’s not possible for your order to be delivered on a specific date, or within a specific 3-working-day range. In instances like this, we'll despatch your order as soon as we can, although we can’t guarantee delivery on a specific date.
Unscheduled delivery is often selected for you because we can't process your order straight away. For example, when the item on your order is out of stock.
