I got a couple of vouchers recently from lovefilm and I still have one left. No catches - you just sign up and give them the code then call a few days before the time is up and they cancel it. Used one myself at the beginning of the year and apart from a few minutes of gentle persuasion it was easy enough to cancel. 3 months of up to 3 dvd's at a time - and as many as you can watch - you get a first class envelope to send them back in. If anyone wants it let me know and I'll send you the code.
