I was looking for an advanced fair from North Wales to London. In the week, the price quoted, with a rail card, was £89.90. It suddenly went up on Saturday morning to £107. I booked thinking it would only go up more -only to find it went back down on Sunday.
Hmmm, looks like the prices go up on Saturday when people are off work and more likely to go on line, or is that me just being cynical?
