Maybe it would help if the shipper listed the contents on the outside of the box.I was highly insulted last year when the pirate opened the box, rummaged around and apparently decided there wasn't anything in there he/she wanted. Hmmmph. My packages aren't good enough for you?
Not saying it's a bad idea... maybe a very good one. I simply don't understand how it could work. You can't bestow a key on every delivery person who may bring packages, nor can I see putting a note somewhere that tells a deliverer where the key is kept. Then too, they'd have to be sure to lock the p-mailbox up every time they left a package.A rational idea would be to have a package mailbox of some kind outside your door maybe with a lock and key.
