Not sure if you can get the same thing from Brum but from London, if you go to the Megabuss website and put in London to Southampton, the date and route "any" it will pop up with TRAINS for anything from £7/£11/£15 singles depending when you leave and return, you print off your ticket take it to the station and fanny's your aunt you avoided paying £40 plus with South West Trains. A couple of our London Lions are doing it for the game.
