Thieves sell the craziest stuff. If only they applied their effort and work ethic to something legal...
A friend of mine who works for a major grocery chain told me that they were having troubles with stolen pallets. I thought he meant the wooden ones and said "what else is new?", but he said it was the new composite ones made out of recycled plastic.
It turned out that they were losing so many of these pallets that they started putting trackers on them (like LoJacks) so they could follow them. The pallets were being stolen from California and trucked out to the middle of nowhere in Arizona to a makeshift facility (picture Breaking Bad) where the thieves ground them into pellets and sold them back to the Chinese factory who manufactured the pallets.
The chain was: Chinese factory >> grocery distributors in CA >> grocery stores in CA >> thieves >> Arizona facility >> back to China >> repeat.
I got this story from the friend after I returned a couple of green totes that I stole from that same grocery chain back in the 80s when I was in college before you could just buy them at Target. I was cleaning out the garage and didn't need them anymore, so I figured he'd get a kick out of my coming clean and returning them to him. He said that those totes are still worth big bucks.
He turned them into Loss Prevention and a few weeks later they literally gave him a trophy to present to me for "found revenue".
I'm living a clean life now though. No more stolen totes. And your catalytic converter is safe around me.
