Query: No need to buy If .....

No need for those who already owned Harry Potter DVD separately to buy this box set edition. I have bought the box set which contains 3 of Harry Potter movie and found nothing different with the 3 Harry Potter DVD which sold separately. I just wait for Harry Potter DVD collection box set which contains all Harry Potter movie : 1 - 7 release in Uncut/Unrated Version and DTS surround sound.
