So I'm thinking... I could pay $.37 x 4 for stamps and just put them in the mailbox but that seems pretty silly. I would essentially be paying the post office to walk 30 feet inside the building and put them in the appropriate PO box. So I go down there to see if I can't put my bills in the appropriate PO boxes (through a little slot or something) myself, and thus save the money. No go.
So today in the morning we decided to go to Thriftway and get donuts. As we're walking out of Thriftway there are about 8 wooden mailbox things with all the appropriate service (water, gas, electricity, phone, cable, etc) companies labeled. They have a little one stop bill drop off. It's all community run, so it's free. One of the nice aspects of living in a small community. That's almost reason enough right there to shop there.
