Heads Up: 3 ODEON Cinema Tickets For £12 @ Groupon
The Groupon tickets can be used from 2 May – 17 June 2015 inclusive at the cinema box office to admit the authorised bearer to view any advertised performance of a standard 2D or 3D film showing at an ODEON cinema in the UK, except: ODEON Leicester Square, The Lounge at ODEON Whiteleys and BFI IMAX.
You can't use it to watch Avengers: Age of Ultron before the 15th May; or any showings of Jurassic World and Minions. You will also have to redeem your tickets at the cinema box office, not online or via the apps.
You don't have to use all three codes on the same day, and you don't have to use them all in the same visit - but you can. You can also use two in one and one at another time.
As far as I can tell there are no restrictions on using it over the Bank Holiday Weekend, so if you are looking for something to do on a rainy bank holiday, buy your tickets first thing!
