Shipping companies sometimes seem determined to smash things. There is a company (I will not name it - only say that it felt like there was a Canada Post shoved up my arse) when I heard it had happened again... we were shipping carbon XC ski poles across the country... the first set arrived broken - no problem, $#!+ happens... send another pair with a long stiff folded cardboard reinforcement in the box- BROKEN!... next set include a 2X2 peice of lumber in the box as reinforcement... can you guess? BROKEN!!!

All sets paid for by the company (a Crown Corp, so actually paid for my me), but a pain anyway.

Pack assuming the box is going to be run over by the truck before they even start trying to damage it.
