Items marked as "Back Order" or "On Order" are not currently in stock at any of the warehouse locations. We have ordered the product from the supplier, but have not received a date yet as to when, or if, we will receive this product. We will update you periodically on the status of your order via eMail. If the supplier is unable to fulfill an order, your order will in turn be cancelled. While we regret cancelling any orders due to a shortage of inventory, sometimes these circumstances are beyond our control. Therefore, any items you require in a timely manner, we recommend not be purchased if on Back Order or On Order status.
