Theatre for the financially challenged

I have an expensive theatre habit as regular readers may have guessed. Many a DIY job sits undone because there is always a play I'd rather spend my hard earned cash on and I still don't get to see everything I'd like to. Naturally, I'm always on the look out for cheap tickets or discounts. 
And this innovative deal from the Southwark Playhouse, which is a fab tiny little theatre tucked under the railway arches near Waterloo Station, got my attention (thanks to theatre buddy Debbie). I've never seen this type of offer before, but the way it works is that you pay £35 and get five tickets to see any shows at the theatre. That's just £7 a ticket and there is no time limit on when you use them.
The only restriction is you can't use more than two tickets for any one show, so you'd only be able to take one other person but as I quite often go on my own anyway that isn't a problem.
Its a great idea and one that definitely appeals especially as £35 barely covers a decent seat at one of the West End theatres (Waiting for Godot was £52!). I like good seats but Southwark is such a small theatre you are always going to be close to the action.
It's pay day tomorrow so I'm going to sign up. Will keep you posted as to what I go and see.
