Can I use an oyster as far as potters bar?

[KatyMac]

Umm that's it really?

No. Hadley Wood.

Thanks do I need to get out at Hadley wood to touch out of oyster?

I guess I can buy a ticket before I get on for the part journey?

You can use contactless though

Aw thanks but we can't - because we have a discount on our Oysters & we are also discounted on buying ordinary tickets we can't use contactless
