For anyone interested, New Little Kings Story (excellent game btw! I've pumped a lot of hours into it) has been reduced at Shop To
http://www.shopto.net/psp/PSPVLI03-new-little-kings-story-ps-vita
£21.85 is a good price, most places are trying to charge £40 now as it's a less common Vita title as it had a small production run and is digital only in the US.
