We are not liable for packages that are not received but are tracked as "delivered". If there is no signature requirement, FedEx will determine at their own discretion if an area is secure to leave a package. If there is a signature requirement, they will attempt to obtain a signature from someone at the address or nearby. If they aren't able to obtain the signature, they may leave a door tag with further instructions. Check your tracking info for details on the latest delivery attempts. If a package is marked as "delivered" but cannot be located, it is likely the package is nearby or may still be on a delivery truck and is not yet lost. Often, the package will be delivered the next day. If the package still cannot be found, it is your responsibility to contact FedEx and request a "trace" to locate the package(s).
