Check out O2's Priority Moments, sometimes National Express do a one way fare of £10 from London to Glasgow.
That would be good if I can get them but I'm not sure people that aren't on O2 can qualify for their offers.

Though it may be a useful emergency number for my spare phone while out and about.
