Amusingly enough I've had that method fail while ordering an iMac a few years ago.
I requested delivery-with-signature on a $4k iMac and it got delivered to another house three blocks away. They didn't ask for the signature (though they were supposed to); they just left a $4k computer on the curb. It was marked as delivered. I'm lucky to have an honest neighbor who brought it to my doorstep (no thanks to Apple and their logistics partners).
