That level of packaging was fairly common when I was getting players in for service. I'd get one like that every month or two. I ended up putting a note on the shipping instructions saying that oversized packaging wil result in you being charged extra for shipping if it cost us more, although I never actually did charge anyone.

I've also had players sent rattling around in FedEx boxes and even just wrapped in a plastic bag with a label stuck on. Amazingly they survived undamaged.
