Just a word of warning to anyone who has booked train tickets on the First Great Western Website in the past few days, using a railcard - you have probably been seriously overcharged.
They relaunched their website on Thursday, and since then if you try to book a journey using the form on the home page, even if you input details of your railcard, the prices that come up do not include the railcard discount - but there is no way of telling that unless you know how much the journey should cost.
I told them about the problem on Friday and they still haven't fixed it.
I was booking a trip I have done many times before, so was shock when the tickets came up as double what I was expecting to pay (more than £260 rather than £130 or so). I found that if you use the advanced search option on the website, rather than the main booking form, it comes up with the correct prices, but I presume most people just use the obvious option on the home page.
If you have booked anything with a railcard in the last few days, go back and check the prices using advanced search, or call them instead.
