Unfortunately, once the order has been placed the payment has been finalised and we cannot add anything else to the order.
That being said, we'll do our absolute best to help! If the order hasn't already left us you're welcome to place a new order and let us know the order numbers of the orders that need to ship together.
Please note that the orders will be a split delivery.
If the order has left us, unfortunately, it is out of our hands.
