Yeah, I think I am finding out the hard way. There is nothing wrong with cash being sent through the mail or a legal conversion kit for my cows so I believe mine should get through but next time I will go with UPS or FED-X
I've used USPS many many times before. Only had one lost package in seven months. Have been using UPS/FED-X for cash and packages much safer and not as much of a legal issue if you grt bagged...
A 2 day UPS from Colorado just took 8 days to get here to PA ( not AS related ) and my new lever action belt took 2 day ( though it was sent 3 day ) from Washington state .
