Frugal entertainment helps me slow down, relax and sleep better. Going to these sites for me is like watching what is playing:
http://www.archive.org/details/feature_films
archive.org (Wide variety of media)
librivox.org (Audio Books)
gutenberg.org (EBooks, AudioBooks)
Also I listen to podcasts sometimes. What do you do for frugal entertainment ? When we are here, let us also have some fun. :)
