Who make's money out of music? It seems it is rip-off ticket agencies
See tickets seems to be one of the worst. This £6.50 face value ticket would have cost less than £7.50 from We Got Tickets (if you could buy it from them) from See tickets it costs £11 + optional but pre-ticked insurance = £12 This means that See tickets take 45% of the punters cash.
Why would a promoter/venue use these people ? If you are a promoter who does, perhaps you could tell us.
