Unfortunately we are unable to combine multiple orders or add additional items to an order once it has been placed. We are only able to cancel orders and/or cancel selected item(s) before the order has shipped and you must call to cancel your order. Once an order is canceled, it may take up to 24 hours before you are able to place a new order for the same items. Please note, if you cancel your order, you run the risk that your selected merchandise will be out of stock.
