Not as good as previous deals but Argos are currently selling Now TV boxes with either a 4 month entertainment pass or a 3 month movie pass for £19:99.
These may not be as good as you'll find vouchers for on Ebay or the like but I've found the vouchers inside these boxes last at least 12 months whereas its hit and miss on how long you have to apply one to your account when you buy the voucher alone online.
I've just added a 6 month entertainment pass and 4 month movie pass to my account from box and voucher deals purchased from Argos (for the same £19:99 price) in October 2016 so in some circumstances they can last longer than the 12 month limit.
Edit:
Talking of Now TV they have a Black Friday deal for new customers only, 12 months movies for £55, 12 months entertainment for £45 and 12 months sports for £199.
If anyone is thinking of switching to Now TV £300 for that lot for a year seems a very good deal to me
