[silverfoxcc]

I am making a very rare trip outside the oyster zone this Sat
Proposed route
Kew Gardens-Finsbury Park via NL line ( avoiding Zone 1)
FPK to Stevenage .

and return

Oyster on the first leg
GN on second
Question is, can i buy a FPK-Stevenage ticket on line and if so what station can i get it from prior to Sat?
My local station is Bracknell

Any Train operating company site can sell a PFK-SVG ticket. You can collect it from any station with a ticket vending machine (there are some TVMs that don't offer this facility but that isn't relevant here given the journey that's being made).

It'll be simpler if you use Oyster to Highbury & Islington (tap out on the platform validators) and get a paper ticket from there to Stevenage. It's the same price and will save having to tap out a the gateline and re-enter straight away with a paper ticket.

You could also buy a through ticket from Kew Gardens to Stevenage (route Camden Road) for £17.80. A few pence more expensive but saves having to tap out/in mid-journey.
