When you order a product or products, you must indicate if you authorize the shipping provider to leave the package if delivery address is unattended. You can do this by clicking the “Yes” or “No” checkbox in the “Unattended Delivery Authority” in the Cart prior to Checkout. If you do not authorize the shipping provider to leave the package if address is unattended at time of delivery, check “No“, and the package will be marked “Signature required” at the time of shipping. If the delivery address is unattended and a signature cannot be provided at time of delivery, the responsibility rests with you to make arrangements with the shipping provider for subsequent delivery or pick up. Extra costs incurred, if any, are your responsibility.
