Ztrack Center ships all products (Domestic and International) USPS Priority Mail, insured with tracking. We are unable to ship UPS, FedEx or overnight. All shipping charges are based on the value of the purchase, not the size or weight of the items to be shipped. We do attempt to ship all orders within 24 - 48 hours after the order is placed. High volume periods can affect fulfillment. Customers will receive tracking information emailed to them via USPS.
