This deal was posted yesterday but without the glitch. Cineworld have emailed me a voucher code which is FREEBIRDS-2FOR1 , which gets you buy 1 get 1 free tickets for freebirds. Unfortunately we wanted to go and see frozen so i tried using the voucher code and it worked. If you join cineworld online (its free) you also save 10%. So you get 2 tickets to the 3D frozen for £8.37 instead of paying in the cinema £18.60.
