You can place an order for an item that is out of stock.  Enter the quantity you want to order and click add to cart.  You will get a pop up message that says, "Production Warning.  Please note that you have ordered more than our available quantity."  Click confirm on this message.  The item(s) will be added to your cart.  When you checkout, you will select if you want partial shipment or to wait until all is in stock.  

Note - If an item is out of stock and there is no "Coming" date listed we will move up production once there are back orders.  Back orders are filled on a first come/first serve basis.
