The thing about CP leaving packages sitting around is true. I had actually done an order before, which included a gun, and the tool left it sitting on my front porch in plain site from the street. No one was home at the time, only once in my life did I get a notice, and that was about 5 years ago. Ever since, they just leave it sitting around. Few weeks ago I did a small order (big packages though) but instead of leaving it on the porch, the poor moron tried jamming them into my mailbox, had I not got home, I imagine both packages would have been gone.
However they do knock.. once.
