Once an order is placed we are unable to make item/product changes to it. However, what we CAN DO is cancel and refund the existing order* so you can then place a new order. It is always best just to place another order if you need to add another item or make any modifications.
If you need to cancel your order for any reason, please notify us as soon as possible. While we cannot guarantee it, we will do our best to fulfill your request and cancel the order prior to shipping.
