I'm a FEEBAY seller so I know all about packaging things. Extra tape extra cardboard and lots of packing material are the norm. With wrenches and sockets I would use some of my millions of wire ties to make sets so they would stay all together if the boys got a little rough with the box. I forgot about the if it fits it ships thing. I send mostly small things through USPS and big items I do FEDEX. For really big items I throw them under a bus. None have lost anything on me yet. FEDEX did damage a hood on me though but they paid for it.
