Ok dont think its been mentioned here and didnt know if its freebie since you have to buy other items, but if you buy both Crimson Wing and Toy Story blurays, input the magic rewards codes inside and you will get Pixar Shorts Free!
plus if you purchase another 3 eligible blurays from the Bogof around at the moment you will have enough points for another FREE bluray.
Basically sign up to disneymovierewards and you get 50pts for registering and 50 morr for a short survey. then input codes from 4 blurays that have codes (full list on their site and most are in bogof right now) and you will get to 700 pts which entitles you to any one of these Blurays
Meet The Robinsons
i think there is one more too cant recall right now.
basically you can get 7 blurays for price of 3, its worked for me.
