If you really need six day a week delivery, then rent a post office box.

Excellent idea.
I am guessing that most residential postal customers could do with just weekly mail delivery. At our house alone, I would estimate that 2/3 of the items received are junk mail, which goes right into the recycling bin.
I do frequently call catalog senders and tell them to take me off their mailing lists.
My mail is basically three categories: buy me, give me and pay me. All but the third category (and the occasional nice letter or friendly greeting from friends and family) could wait weekly.
