Nielsen numbers for box sets
What do box sets do to the sales numbers? Sets like Spidey and Die hard give you 3 or 4 movies, but only counts as one sale. I know Spidey doesn't have individual sales for 1 and 2 right now, but Die Hard for $90 as a single sale seems like the sales numbers will be a lot lower than single movies. How exactly do these work for the numbers since all the Die Hard movies will be sold individually?
