I ordered this DVD and received a substitute I never received the DVD I ordered from Importcds (the Vendor). I contacted them and did not recieve any feedback. I can't rate a DVD I have never seen. I didn't bother to send it back because it would have cost me more that I orginally paid for it. In the future I will watch for the name of the person and/or persons I am buying from. I thought they were a good company. I understand a simple mistake but, to not get a response at all is not good businees sense. I spend hundreds of dollars a month on Amazon.com building my DVD collection. I guess I will be more careful in the future.

Ex Output:
