Topcashback are now offering £10 cashback for doing a free 30 day trial of NowTV. So you can get 30 days of free movies and a tenner in your pocket. Bargain!
If you're not a topcashback member yet, you can also get an additional £5 by signing up via the special link on NoBrainers.
Having just completed a free trial, I think the movie offering is much better than Netflix. Don't forget to turn off the 'auto-renew' once you've signed up so that you don't end up paying for the subscription once the trial has expired!
