I've not got Now TV but I'm close to picking one up (mainly for the Sky Sports pass). Are you able to "stack" passes, say if I buy 2 x two week sports passes, can I enter them both and they stack or will one overwrite the other ?

Or, will I just have to re-new once my current pass expires ?

You can't enter another Sports pass whilst you currently have Sports. What you will need to do is enter the second code afterwards. This shouldn't be much of a problem as the week passes (and day passes) don't auto renew so you won't be billed any extra. And you can always hold on to the second voucher several months down the line. (The only issue is if you start pass 1 at 5pm on Sunday, and really want to watch the 4pm kickoff the week after as you'll need to enter the pass 2 as quickly as possible to continue watching).

At the point your Week pass expires, access to the channels will cease. At that point you'll be given the option to subscribe or enter a voucher code - once done the channels will again be available to view.

There's currently no auto-stacking...which admittedly would be a helpful feature!

Thanks for that.
