I remember some internet guy in the mid 2000's claimed he did this to a company that wouldn't stop mailing him these things even after asking numerous times. So he went to the junk yard and picked up a handful of old refrigerators and slapped the mailers on the side. He said they shipped, costing the company a small fortune. The company tried to sue IIRC, and I want to say the judge was like basically "nah, this guy asked you to stop".

I believe they changed the rules in the US so that you wouldn't be able to do that anymore. But like you said, the trick is to find the max weight they'll ship.
