X-men origins wolverine question

[Tdonnelly3]

Does anybody know the difference between the 3 editions of wolverine?

Am i correct in thinking that the one available everywhere was just a single disc blu-ray?

The play exclusive was a triple play with the same artwork as the single disc?

And the hmv exclusive was a triple play with different artwork?

The reason i ask is i picked one up last week for a fiver, its the triple play (2 discs) with a slip, has the same artwork as the normal version but the details on here list the play exclusive as having 3 discs, was just wondering which version it is?

Apologies if this makes no sense
