I have 2 spare tickets for Camera Obscura tomorrow (Thurs 17th July) at Kings College, London.
I paid £10.50 each for them, plus booking fees £4.27. £20 and they are both yours...
To make it more difficult, I can't get to the venue. I work around Waterloo, so am happy to hand them over near the station in person at lunchtime tomorrow, or at about 6PM. I live in Stockwell/Oval, if that makes it easier. Anyway, if you're interested let me know, and I'm sure we can agree something!
