Before contacting us about shipping and delivery related issues, please contact the delivery service directly (check your tracking number for either USPS or UPS) for further assistance, as once the package is picked up from our warehouse and input to their system, there's not much help we can offer. For more information please reference our Shipping & Return Policies.
