Aureolin's £6.20 figure was based on a Red & Purple 2 Zone BuzzFare - the only day ticket which is available to use on the X36 service between Boldon and Newcastle.

I know, but I doubt many people would buy a day ticket for a journey between Boldon and Newcastle, and opt for a return. Whereas, on Stagecoach the daysaver is the only option, so it's only 70p difference.
