Ya know .... I know this is going to sound like Black Helicopter stuff, but you see these low profile but amazingly stupid ebay auctions all the time and then they SELL. I remember one from Germany a few months back were the guy got 500 dollars plus for a dropped and totally destroyed Leica body. Made no sense.
Are people doing this to transfer cash quietly around from country to country? They make an arrangement to "sell" some bit of junk, then a partner buys it and sends a big (but not TOO big) pile of money for it. It looks totally legit and in order, no one has to risk handing off dirty money, and then buyer/seller simply start over with another account. Everyone is clean, with little risk.
I know, a few hundred dollars ain't much, but if you're paying off a helper or greasing a local cop, then it might work.
Okay, I'll go back to my spy novels now....
