I always knew Londoners got ripped off. But I was looking at some train tickets

recently.

You can buy an advance rail ticket for 07:15 travelling from Liverpool to London tomorrow morning for £7.50

But if you wanted to travel from Reading to London it would cost you £23.60

Yeah but you earn more in London etc....................

Or more people will travel from Reading to London than Liverpool to London, so supply and demand means they will charge more
