I wish to buy some advance train tickets from Virgin Train, travelling from London to Liverpool. However, I cannot buy the Railcard (which enable discount on train travel, even for advance ticket) yet as the Railcard cannot be sent to outside UK address. I can only buy it upon reaching London at a staffed rail station.
Is there any rules which forbid buying train tickets first, then get the Railcard in time for actual travel?
Many thanks in advance for the answer?
