Have you actually seen a ticket at that price? The cheapest tickets I can see for today are £39.85 and for next Tuesday are £35.50. Presumably there are some £12.50 tickets available, but they're not easy to find (my understanding from folks who do more train travel to me is that tickets are released some number of months in advance and the cheapest price bins usually disappear pretty quickly). If you want to travel at peak times, the prices are much higher.
