Most people steal 'em.

I'm a programmer / designer for plastic injection mold builder, we've built several crate tools
in the past few years. There was an article about theft in one of trade papers a while back:

"The story says U.S. dairies lose about $80 million annually to milk crate theft, and that one company in California has hired a private detective to track down lost crates. The story's sources blame the problem on recyclers in China."

I think I have some video of some tools running production, if I can find them I'll post a link.
There kinda' cool to see running, if you're into mechanical things.
