if you book your train tickets a couple of weeks in advance, I would guess about £15 - £20 for london to chesterfield.... that is only a guess though ;)

yeah 14 day advance return ticket is £15 :) just dont go to GC in shoes, trousers and ben sherman shirt... look cool & as original as possible. also, contrary to popular beleif, u dont have to go cyber to get in :)
