After 4+ years of ordering online, I've only had to sign for one shipment.  It was a JAC mod from Scotland.  This was the second time ordering from them and the first JAC didn't require a signature.  I have a large mailbox located at the beginning of my driveway and can handle a rather large volume of mail.  If it can't fit in the mailbox, then the carrier leaves it at either my garage door or front door.
