I had to make a video on how to package medium flat rate boxes on our website because the mail person will hand me an empty box even though it has a stamped weight of 50 to 70 pounds on it FROM THEM. GET INSURANCE!!!! but be very aware that it will take more than a year to receive your claim. When people package it like I explain in my video it gets to us in perfect condition in three days every single time. Oh and to be very clear we are talking about the United states postal service! I learned a long time ago that you can't abbreviate it or everybody gets it confused with UPS
