Those are both illegitimate. IIRC, the “Limited Edition” was never sold in a set, and not in skinny packs.
Yes they were, in 2008. I saw them in fye and Best Buy countless times before they were pulled before the BD release. There was a prequel set and an original set, the latter containing repackaged versions of the 2006 DVD sets. That aside the 2006 sets was also available in a tin case at Best Buy when they first came out (I know cause I have it).
Ah, interesting. So that outer box WAS official?
Yep 😃 On a few occasions I was even attempted to get those sets, at least the one for the original trilogy, but passed because there wasn’t anything new I was technically getting
