Yes, more same than different:
- Same artwork.
- UK edition not available to order at this time,
Italy edition available and certainly cheaper @GBP 17.53 + P&P (instead of the Zavvi price of GBP 22.49 before discount code).
- Amazon.It reportedly uses a basic A1 cardboard mailer for dispatch although I've read that they sometimes put the steel inside a padded envelope before placing in the cardboard envelope (although how that package would fit inside a standard-size mailer is puzzling). Zavvi's white cardboard boxes have carried hundreds of steels to my front door without incident.
- Obvious differences with the j-card (no certification stamps and language other than English).
- Both to be released around the same time (the middle of June).
- U.K. edition according to the BBFC "This work was passed uncut" and I presume the Italian edition is likewise uncut.
- Apparently over 3 hours of Extras plus four, yes, four, audio commentaries on the U,K, edition - unfortunately, unable to find info on the Extras and Commentaries on the Italian edition.
Looks like I was quite wrong about the possibility of this steelbook having a shared print run with HMV as HMV are now showing their own exclusive - in this case an Amaray in a slipcover with exclusive "Deadpool" Artcards (due out same time as Zavvi's steelbook) in a package currently priced @GBP 14.99.
The same style DVD package is priced @GBP 9.99 - also with 4 Artcards - but haven't the foggiest idea if it's the same 4 cards as with the Blu-ray or a different 4 . . .
Looks to be the same package as the U.S. Target Exclusive apart from the lack of a DVD - what a surprise . . . not - and only 4 Artcards instead of 8 with the Target.
