Brilliant price for all 8 films in SD (or £14.99 for HD).
On the Google Play Storefront there is a banner advertisement for Cyber Week to get 'Half off any movie to own' which when you click you'll be taken to a page of movies to select. Ignore these and find this collection and once you get to the checkout the discount will be applied.
Alternatively you could try to use the code CYBERDEALMOVIES2016.
Must be redeemed by November 29 2016.
