No, It is not possible to specify a delivery time or day when you place an order with us.
Once your order has shipped you will receive a shipment confirmation email which will include a tracking number. You can use this tracking number to monitor your delivery through the the carrier's website. From there you'll be able to see an estimated time of delivery, and if you wish, change the delivery day to suit, or arrange for the item to be left in a safe place or with a neighbour, as well as sign up for SMS alerts as to your deliveries progress (where provided by carrier).
