Do you 'borrow' e-books from your local library? Does your library have such system? Nashville has a great digital library.
I really wish my local library had something like this. I love physical books, but reading something on my Kindle is so convenient.
It depends which library though because not all of the local libraries offer e-books for rent. I do usually borrow e-books because I know I won't be able to finish reading it in less than two weeks. I would rather purchase the physical copy or e-book so I can read and finish whenever I want to.
