Home delivery is obviously at the top of the list of five. If I had to rank the five, I would then very quickly say community mailboxes. It's been my observance that community mailboxes are fairly close to the neighbourhoods, so they're not too far away from your home address, notwithstanding the other complexities. The end of the laneway would be my third-ranked one, I guess.
