Since orders are processed automatically and sent to the Amazon Fulfillment Network immediately we can not add additional items to your order.

If you really need  to change a order the only thing we can do is try cancel the order and have you place a new order. That said canceling an order once it is processed by Amazon generally does not work, in which case the order will be shipped to you and we will provide a prepaid return label to return the order for a refund if needed.
