Movies, when released for streaming, usually (not always) have 2 options - "purchase" and rental. If I am correct for new movies only "purchase" sometimes available first and rental often comes with some delay.
For TV shows, however, I see no rental options. For instance "Falling Skies" season 1 and 2 are available as a part of Amazon Prime program. Season 3, however, is only available for "purchase". I have no interest in "buying" it because I am not likely to watch it again (and I also refuse to "purchase" any media that requires internet connection for playback).
Are there any streaming providers where latest seasons of shows can be rented for the price smaller than the "purchase"?
