Please ensure the accuracy and currency of your shipping and delivery address. While P.O. boxes can be utilized as shipping addresses, specific items may necessitate delivery to physical addresses. Large products, valuables, perishables, items with age-based restrictions, or those dispatched via private carriers may mandate a physical mailing address or signature confirmation for successful delivery. Additionally, certain merchandise partners may specify in product listings that they are unable to ship products to P.O. boxes. Deliveries to security-restricted areas such as military bases are not feasible.
