The person shipping its his fault in my opinion. I order lots of parts and sell lots of parts. About 50% of the time I recieve packages. I see a person that spent 30 seconds to pack and another minute to secure with tape. The box is barely in one piece cause of shipper not taking an extra 5 minutes to tape the box up.
In the case of front brake parts, heavy with sharp edges to break open easily. You tape the shit out of the box so it doesnt open, very simple. Problem is people are do damn lazy to do the right thing!!!
Its not the post office fault the idiot doesnt package it well for shipping!
