Always found this problem quite interesting. In the UK, parcels are rarely if ever left on the porch. If you aren&#x27;t in there&#x27;s a few options: a) they deliver it to a neighbour and post a card through your door saying &quot;it&#x27;s been left at number X&quot;; b) they leave it in a safe space (typically throw it over your garden fence); or c) return it to the delivery office for you to specify when to redeliver or pick it up yourself.<p>Can anyone shed any light as to why (a) doesn&#x27;t seem to be used in the US?
