Don't worry, you won't miss out if you're not in 😃. 

The delivery driver will leave your order without a signature as long as they are confident that the area your parcel is left in is safe and secure. They will leave a card as well just to let you know where your parcel is. 

If the driver isn't happy that there's a safe enough place to leave your pawsome presents, they'll take the package with them and leave a card for you to either pick up at your local post office or re-arrange delivery.
