if the guy is lying, which i'm almost sure he is, how can you really prove that it doesn't work? unless you find someone that works for ebay and plays d2 so you can give him the dupe to let him try(assuming anyone at ebay gives a s*** about you), then it's kind of hard to prove that it doesn't work. he could just come up with all kind of bogus claims like oh you're not doing it right, or it just won't work with your comp cause it's to slow, or your anti virus messed it up. and also i've heard that ebay doesn't have a policy on physical items, and since this guy's only got 2 feedbacks(which probably came from accounts he made himself) i wouldn't buy it unless you don't care if you totally lose that $30.
