Can someone please explain why all the Oyster fares to the four c2c
stations which are outside the Travelcard zones but inside the Oyster PAYG
area include validity within zones 7, 8 and 9? These three zones have
absolutely nothing to do with c2c, and the number of people who need
validity e.g. to Grays *and* to Zone 9 must be vanishingly small. The
area containing these four stations is contiguous with Zone 6, so why not
(for example) "Zone 1-6 + Grays"?

Having said that, I see there is a Zone 6 + Grays fare, but it's the same as
the Zones 5-9 + Grays fare!
