From September 6, FCC pax from outside the Travelcard Zones heading to London during the weekend can buy interavailable Super Off Peak Day Returns/Travelcards (saving roughly 20% from Luton Airport Parkway for example) and get Railcard discounts on them too. Unless you're travelling from Peterborough.
Until then you can buy FCC-only Super Off Peak Day Returns/Travelcards for weekend travel but can't get Railcard discounts (or NXEA-only tickets if you're travelling from Cambridge).
