To celebrate the start of 2019, all our exclusive t-shirts are just £3π (that's £9.42 in real money) and our exclusive tote bags just £τ (aka £6.28). Once they're gone they're gone, so don't miss out.

You can also buy a triple bundle of all three of our shows for a reduced price, on DVD or luxury download gift pack - and add a tote bag for just £3.14 extra. Our latest two shows, Just For Graphs and You Can't Polish A Nerd, are also reduced by a whole £π. 

Fill your boots!
