Absolutely, you can even cancel after 2 weeks and the pass will expire before the next payment is due.
What you need to bare in mind is if you cancel and leave it a month or so, the offer will not return. Unless you are lucky to come across a new offer to sign up to.
Now TV has switched to a account by account basis on offers. So it will come and go.
FYI that I do not work for NOW, just a NOW customer trying to help
