I found this while I was browsing the web. Lovefilm are an online DVD rental company - you choose films from their website, they send them to you,. you watch them and then send them back.
On the website they offer a 14 day free trial. BUT - if you put the code below in, the 14 day free trial turns to a 90 day free trial! I'm using it at the moment, so it does work. I'm sure there are a few of us who could use a few films to fill a few hours and provide some distraction, not to mention the fact that it's completley free - just remember to cancel your membership before the 3 months is up
