10 years ago, I moved back east from the west coast of Canada. I used 2 cubic foot moving boxes, and literally dumped the contents of my desk and cupboards into them. I sent all 25 boxes by regular parcel post to my parents' address, then loaded my car and drove with the rest of my stuff. Not one box cost more than $24 to mail (most were 15-$20), and they all made it within 1 week with no damage whatsoever. I made absolutely no attempt to pad anything, and not a single item got damaged. I suspect if I were to try the same now, it would cost many times more, and I may not be so lucky with delivery time or condition.
