I've just seen the following answer in response to a question about train fare:

A: The cheapest available fare for 1 adult from Yeovil to London on Saturday 29 November 2008 is 10.00 GBP. thx

So either
(a) They are giving their customers information that won't actually be any use
(b) They have discovered the secret of TIME TRAVEL
or (c) They are recycling old questions

I would like to think it was (b), but I suspect (c) is more probable.
