Adding a signature to your delivery is optional. Adding a signature requires someone to be available at the time of delivery. By opting to NOT to sign for a delivery, our CUSTOMERS ACCEPT LIABILITY for porch or mailbox delivery. With the dramatic increases in porch thefts in recent years, especially during the holidays, we encourage all of our customers to sign for delivery to guarantee delivery. If a carrier posts a status of DELIVERED and SIGNATURE REQUIRED was NOT selected by the customer, the customer will be responsible for working with the carrier to locate the package.
