We do not require a signature for delivery on any order. The decision to leave an unattended package at your front door is solely up to the discretion of the driver. If the driver feels it is safe do leave the package, then they will do so. We are not responsible for missed deliveries because no one was home and the driver felt it was unsafe to leave it.
If you plan to be away for the day of delivery, it is your responsibility to arrange for someone to pick up the package and freeze or refrigerate the items as required.
