There are several reasons why a shipment might be delayed. Typically, delays result from order-related data discrepancies. For instance, if incomplete shipping information is provided such as a missing apartment number or the incorrect zip code, your order may be delayed. Your order may also be delayed if the item you order is on backorder / preorder or out of stock. If the item is out of stock and we will not be receiving any more, a customer service representative will contact you.
