I don't know that "cheap" is quite the word you're looking for. There are plenty of folks on (extremely,) limited budgets (students, oldsters on Social Security, the disabled. . .) who live alone or isolated, can't get to a theater, and on top of an already expensive monthly subscription fee simply cannot justify forking out $20 for a one-person, one-time play of a reasonably current film (cough, cough, Tar.) If that means waiting until it comes to the free or "cheap" subscription lineup, (or for those without the bandwidth to stream it online,) so be it. Poverty begets piracy.
