You are never ever ever going to beat these people .They have been around a long time before you started going to concerts and will be here a long time after you have gone to that big gig in the sky.
The problems start at the top , above the artist , the managers .Why sell a ticket for £ 10 when I can sell it for £ 100 .These manager aren't Millionaires , their Billionaires and you don't there by taking 10% of your boys earnings.
I've banged on about this for a few years on here .I think I started a thread with Ticket touts are my best friends .You have to use the system , you buy the tickets they can't sell . I have bought perhaps hundreds of pounds of ticket from touts , every ticket they made a loss on . I've stood at concerts laughing at these people sat on their high horses in seats nearer the moon than the stage because they would not deal with touts.
Your always going to get punters buying over priced tickets , money no object , good luck to them its their money and again your never going to stop that
Be a bottom of the tank feeder , grab that £150 ticket for £ 20 , that will happen if you play your cards right.
