Some of the things I order online get delivered by services that use the USPS for the last leg of the route. I'm pretty sure Fedex does this -- Fedex [SmartPost] uses their system to deliver the package to your local USPS main center then USPS takes it to your door. This doesn't help you with Amazon. I'm surprised that I can't find an option at amazon to choose who delivers your package (i.e., can't choose USPS).
