I was a facilities coordinator for a software company in a former life, so I had to deal with all of our shipping and receiving. I distinctly remember a particular incident during Christmas time when I had to drop off our company mail at the local P.O. The gentleman in the warehouse who took the mail from me was also sorting bulky boxed items into several large cargo bins. He would grab a box from the incoming packages bin, then proceed to hurl said box approximately 20-30 feet into the corresponding bin for delivery. I will never send anything I truly care about through the USPS. Good luck
