NowTV are offering 3 months for the price of one on entertainment (£6.99), cinema (£9.99), and cinema plus entertainment (£16.98) until 12th January.
This works out cheaper per month than I've seen it recently (entertainment £2.33, cinema £3.33). Just remember to cancel at the end.
The deal states new customers only but I've been using entertainment for years and it worked on the cinema pass (I didn't try on entertainment)
Apologies if this has been posted but I couldn't find it in a search.
