I've seen quite a few weird listings like this and my thought is that it NOT what they're selling - just something to make the listing look legal.
A couple years ago a guy listed every individual component off a stripped down photocopier. A small gear, a rod, a motor, etc. Every listing was Buy-It-Now for $10,000 each with $500 shipping, I'm guessing that when that crate of drugs (or mail-order bride) showed up that piece would probably be with it.
