I had a look at the offer on Amazon.it, but the versions in the deal are not the extended ones (unless you want to buy them individually), so not really comparable. Some good deals there, though.
Actually, I think that may be the limited edition version.
If you check out the photos, one of them shows the Blurays in the amazon packaging. You can see the Ultraviolet strip on it.
Go to amazon.it buy 3 Warner brothers blu rays get 50% off dark knight trilogy 6.50 euros hobbit trilogy 10 euros just go to blu Ray offers. Or search on hukd it has been put here twice search for Chris Nolan 4K deal.
