You are! I am saving a lot of money getting these king of bundles than if I purchased every movie on a single movie case. I paid about $20ºº for X-Men First class blu-ray and $40ºº for all the 6 movies on a Xmas special... It's also cheaper when you need to pay for the shipping!
I think it's a little silly to have them all in one box when there will be at least 2 more films in the series (Days of Future Past and Age of Apocalypse), but when a series really is over I love having them in one case like that.
