Golf Live 2012 - tickets £20
If you haven't attended before or event heard of it then check out Golf Live for 2012. Tickets this year start at £20 with under 18s free.
I've attended the odd tech conference in the past and paid £80 right up to £399 for a day packed full of speakers, so £20 for Golf LIVE is exceptional value for money.
