right.
i was thinking, as i have an oyster card and a young persons railcard, there's actually no point me getting travelcards on saturday and sunday, because if i get my young persons+oyster sorted then the daily price capping is actually less than the price of the travelcards.

does that make sense oh wise london brethren?

if so, how do i get my YPRC connected to my oyster?

no i wasn't listening the first time.
