You can combine orders to save a little on shipping (the prices listed above is for single orders).
All the Blu-ray discs are region-free as far as I know (searching Blu-ray.com and bluray.liesinc.net). Only Cars 2 has a 3D version in the Car's Director's Edition. Only the first film in The Lion King Trilogy is in 3D. Note the cheaper UK Lion King Trilogy does not include the 3D version.
Reviews on Amazon indicate good looking, but practically flimsy packaging, at least for Cars, so you've been warned!
Bonus Deal: Lightning deal at Amazon UK (available for another hour or so), Star Trek Voyager complete boxset for ~AUD$95 delivered - not the best price ever (and especially crap since VAT isn't removed for lightning deals), but maybe for those that missed out on the lower prices a few weeks ago. Go to this page to access the special pricing. Edit: someone else just posted this lightning deal, I was too slow!
