Typically, orders that have been submitted and processed cannot be altered. Once you place your order and if everything is in stock, it is sent directly to the warehouse where we are unable to make changes to the order. If your order has a backorder we will make every effort to change your order for you. You can send these requests using our Customer Service Center to contact us. Please double check your orders before submitting it online. Once an order is submitted, we cannot guarantee the ability to change the order.
