Really cheap theatre tickets for UK @ lastminute.com
The UK lastminute.com site is having an up to 70% off sale. Only lasts 48 hours but these are really good prices on the tickets which is why I've listed it.
Royal Philharmonic Orchestra £5-15.
Guy & Dolls £15-£27.50
Les Miserables £20 -£52
You'll be paying in pounds obviously and no cashback on the UK lastminute site. Starts Monday 12pm GMT and finishes Wed 12pm GST. I suspect the good tickets will get hammered so if you thinking about going its worth getting in early.
