Abstract: A reinforced bag system and methods of using the reinforced bag systems in package delivery typically to a residence when the residence is not presently occupied are described. The reinforced bag system generally includes a water-resistant reinforced bag resistant to being breached either through a closed top end or by cutting the bag, a cable connected with the bag for use in securing the bag to a fixture such as a porch railing, and at least one lock for locking the bag in a closed position as well as locking the bag to a fixture by way of the cable. A motion activated alarm can also be provided to sound when unauthorized attempts to gain access are made.
