The only thing I tolerate being shipped USPS is motors.
The $37 fee for motors thru UPS or FedEx is nothing but a RIPOFF the govt allows them to charge as a haz-mat fee. They do not have to charge that fee. It's a big can of SCAMULATION.

Many years ago someone shipped rocket motors labeled "model aircraft parts" until discovered.
NEEDLESS TO SAY, I LIKED THAT SHIPMENT METHOD along with the "ride the boot" attitude it conveyed to the gubmint "shipping cops"

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
