I have a Netflix subscription, and they're offering members the chance to send friends free trials.
I'm on one of the cheapest plans: one DVD at a time, but with no monthly limit. It's extremely easy to use - they take care of all the details for you, and the packaging is really economic and clever. Once they get the last movie you returned, the next one shows up in about a day.
I've used it for research purposes (during the Halloween storyline I got the Scooby-Doo movie); I've started seeing movies I wanted to see in the theater but didn't have time to (Thank You For Smoking just went back); I've added movies that are cultural staples that somehow I missed out on (Ghostbusters is in the queue, as are a handful of Bond flicks).
My point is, I love it, and I'm not even being paid to say so. If you have a list of movies you've been meaning to rent (Bram Stoker's Dracula, anyone?), post your email addresses here. I'll have Netflix send the 2-week free trial to the first five.
Did I mention they have TV series too? (The complete Book of Daniel, which was cancelled after three episodes, is in my queue.) And anime? (Chrono Crusade's there too.) And, like, all of Monty Python? (Positions 63 to 79 in the queue.)
Seriously, you should totally try this thing.
