I'm all about shipping safe. And I will admit, I think the USPS is a waste of human fluid and has no purpose that couldn't be filled by competent companies. At this point they are just holding on and trying to finance the retirement accounts of their union members. But what is the most economical way to ship? Is there a happy medium between an envelope and a $4.70 padded envelope (Envelope cost NOT INCLUDED). What exactly am I missing here, and does anyone else have the USPS at the top of their list when the Zombie Apocalypse starts?
