I'd like to unsubscribe from the postal service

One of my favorite Seinfeld bits is when Kramer tries to cancel his mail service.  I so wish it was possible.  The best you can do is hold your mail for 30 days over and over, getting one delivery a month.  Kiri isn't interested in that.  I've managed to reduce my junk mail to Cycle Gear and a couple Occupant flyers.  This year I've kept track of what I've gotten delivered to the house, FedEx/UPS/etc included.  Just to get an idea.
