Just got back from Tesco's where I found Tim Burton's Nightmare Before Christmas Special Edition DVD for just £3.00!! It is in a special Disney "Give the Gift of Magic" card sleeve (with holly and snowflakes so obviously for Christmas).
Just had a look online and for some reason it is still showing as £11.99http://www.tesco.com/entertainment/product.aspx?R=437541&bci=6|DVD
My local Tesco (Norwich) had loads of them!
Brilliant movie, brilliant price!
