3-4 years ago, a few friends and I agreed together to get a membership at the local movie store. This meant we would pay a couple of dollars to rent a movie, and if we were really good, we would get it buy-one-get-one-free! Not too long after we signed up, I was in the library and realized that the library has a good collection of movies and they were free to borrow! I laughed at ourselves for being so silly to get a membership card to the movie store (where I wouldn't watch 95% of the movies anyway), and have been checking the library for free movies ever since:o).
I'm sure this varies from library to library (at another library I had to pay 50 cents or a dollar to get a movie), but it's definitely worth looking into, especially if you like to watch a movie on Friday nights:o).
