Some of the CDRs could, with Railcard/Privilege discounts, be brought
down to below the price of a Travelcard, which has a £4.80 minimum (at
least for Railcards - I don't know much about Priv). So a few might
end up being issued (although this probably still doesn't apply to the
£9.60 ones)

A Priv Travelcard is only avaliable in Z1-6 and is 75p (IIRC) for Kids,
and £2 for adults.
