I there anyone who is keeping track of the "probability of counterfeit" for various categories on Amazon? I've heard that phone chargers almost always are fake, and perfume doesn't surprise me. I'd assume brand-name clothing is suspect. Would not have guessed board games, the market doesn't strike me as big enough to be worth it (though I'm not into board games so I could be wrong).
