Please note, if you are calling about the 2-hour delivery window for your delivery by Costco Logistics, you will receive a 'Delivery Notification' email after 6:00 p.m. local time, the day before your scheduled delivery date. We apologize, due to system limitations, our customer service agents are not able to provide any additional information at this time.
