It looks like if you book in advance of 3 Weeks or More to London, then it'll be £7 There £6 Back, anything less than that, it'll cost you £30, As an Experiment I put in the Date of 20th August 2014, and it was only £5 Each Way, So I am now going to look for the Earliest Date in August that I can get it for £5 Each Way.
