Packaging prints everything on 1 big sheet. Yeah the regular box might be simpler (CMYK passes can be fast + 1 Pantone green) but you still need 4+1 colors.
Ironically the Day One ed might just require 4 colors, but it requires a lot more ink for the whole box and needs to be printed/dried slower...
Looks to me like the Day Edition box could cost more as it also requires a special, for the half matte half gloss finish.
