I just joined NetFlix and it is really fabulous! I came home from work and there were three movies waiting for me. I watched them when I wanted then just popped them back into the mailbox on my way out the door.
I have about 50 movies in my queue and as soon as the ones I just borrowed (Les Miserable 10 year Anniversary Concert, The Lake House, and Capote) get back home safe and sound they will shoot out my other movies on my list.
I seriously recommend that you sign up and get started.
