$99 seems like a lot for a trilogy, that had it's last movie 10 years ago. And that has already had at least one trilogy steelbook released. I realize this is 4k, and that many people probably don't have the trilogy steelbook...but, that still seems steep. I also think it's the 5 movies.
Of course it's not really sold out . . . and still waiting on news of how they're going to cram 10 discs (5 x 4K UHD + 5 x regular BD . . . I'm supposing) into steelbook packaging and if it's to be a jumbo steelbook.
. . . plus four spaces (lol) for HOMECOMING (2017) and HOMECOMING 2 releasing mid 2019.
The Spider-Man films in order of release:-
1) SPIDER-MAN (1977)
2) SPIDER-MAN STRIKES BACK (1978)
3) SPIDER-MAN: THE DRAGON'S CHALLENGE (1979)
