I did not do this intentionally, but if someone wanted to take advatange of it, they could. I bought a Samsung dvd player (stand alone unit, not a drive for computer) at best buy for $199. This includes a mail off certificate for 5 free dvd movies and 13 free rentals from blockbuster. I sent off for the movies, and thought nothing of it. I later bought the movie "Matrix" and tried to play it and it wouldn't work. I returned the player to best buy and they said that they have had a lot of the samsungs coming back because they simply will not play "matrix". So I got a refund, but I still got the free movies coming.
