I know this is super cheeky of me buuuuuuuuut if anyone needs a £10 discount code for TodayTix, you can use mine:
TodayTix provides theatre tickets to musicals and plays up to 30 at incredibly affordable prices. I managed to get tickets to see Evita in its final week in the West End for £8. Who says theatre for students is expensive?!
Have a little browse of the website and see what tickles your fancy, if anything. Have fun!
