At Check out: A "signature upon delivery" has been added to ensure the package is delivered to you directly. By not clicking that option you are liable to file a claim with USPS or risk a lost/stolen package if otherwise.
By finalizing your purchase you are agreeing to be responsible for any lost or stolen packages. A tracking number that says "delivered" or "in transit" means that we are no longer liable for your package. Thank you for your understanding and compliance.
