I really hate when they deliver to the neighbors... I live in a crappy area, one set of neighbors would actually give me stuff, but they never leave stuff with them. The ones across the street and on the other side are pretty sketchy, I actually caught the kids of the one across the street trying to steal mail from my mailbox.
Used to have an excellent ups guy that would either shove packages between the bushes and the porch or if they were too big, drop them in the back of my truck under some cardboard I had laying in there. He'd leave the delivery notice hidden on the inside of the metal part of the screen door that would just say "you know where to find it" LOL. He knew the neighborhood sucked. Fedex & USPS have always sucked and either left it on the porch to be stolen or delivered it to the shady neighbors & I never got it.
Now, unless it is a huge box I know I won't want to carry to the car, I just try to have everything sent to the mailbox rental place here, I have a box there and they will sign for anything (ups,usps,fedex, etc) I have sent.
