Noticed something a little strange over Christmas. Both my brother and I got a copy of Shrek, but they were in two different kinds of keepcases. His was bought at Costco, and was in the standard single case with the flipping plastic (like Galdiator). Mine though, was bought at Wal-Mart, and had a case where the flodout comes out overtop of the liner notes, and the two discs face each other. Does this mean that Wal-Mart prints their own discs? I know that Columbia house does in some cases, since I've seen CDs with different track orders (and sometimes different tracks) from the retail version. Is wal mart doing this with DVD?
