What I would do is have Amazon Prime.
What my family do is we have one main Amazon account between all of us which has my student discount on it (5% off books, DVDs, music, and a few other things), and Amazon Prime on it. So we all get one-day delivery of most stuff, and Amazon instant video. Not *as* great as Netflix, but between Amazon, 4od, and iPlayer I can always find something to watch. You do have to trust each other enough to not order off each others' cards though!
