I was looking at this promotion as it sounded quite good - about 60 places accepting the card in my region, I was pleased to see, when these things are so often London-centric.
However, I was really disappointed to see that the price for under 30s is £45 - whereas the price for over 30s is £75! 
That really is ridiculous when 'over 30s' will include pensioners (could not find a pass for pensioners, only students).
£45 is far more reasonable in the current COL climate. There's nothing on their website to explain why people are being penalised for being over 30 - do they not want the middle-aged and elderly cluttering up art galleries?
Just wanted to pass on the feedback.
