Provided your order has not been processed for shipment by our warehouse, we are generally able to cancel and refund items upon request.
We are not able to add items to an order after it is placed. This is for your security – our system does not retain your credit card information after the card is charged.
However, if you place a second order, we would be happy to consolidate the two orders if possible. Simply send us an email with the new order number and we can arrange for the two to be consolidated and for the shipping charge on your second order to be refunded (if applicable).
