We would like to use the Railcard Travel for Two. Since we live in the U.S., we would need to buy these at a train station after we arrive in the U.K. We would also like to buy our train tickets (e.g. from London to Oxford, etc.) online, before we leave the U.S. The Terms and conditions for Railcards states: "If you are buying online or from a ticket vending machine (TVM) You must declare that You have a valid Railcard by selecting the Two Together Railcard option." So, I wonder if we dare buy the tickets online now, assuming that by the time we want to get on the train, we will indeed have a valid Railcard. Any ideas?
Thanks in advance.
