It appears that in order to purchase the Two Together Railcard that either I need to have it shipped to an address in the UK or go to a "staffed station ticket office". For 30 pounds and 1/3 off rail fares, it will save us about $100.00
The website states.
"You can buy a Two Together Railcard at any staffed station ticket office or National Rail-licensed Travel Agent. You can do this on the day you are travelling.
Please note that Railcards can’t usually be bought at stations operated by London Underground but which also service some National Rail routes. The exceptions to this are: Harrow & Wealdstone, Kenton, South Kenton, North Wembley, Wembley Central, Stonebridge Park, Harlesden, Kensal Green Queens Park, Gunnersbury and Kew Gardens."
So my question, can we buy the 2 together pass at King's Cross on a Sunday? Or at Heathrow? Is there a list of "staffed station ticket offices" someplace?
I have a couple options for delivery to a UK address (work colleagues traveling to the US in the near future), but then it's a bit more complicated with logistics in getting the pass to delivered to us in the US
