Hi there, I have a train ticket to sell, Sunday 22 Dec direct from Geneva to Paris 

(I booked months in advance but have just realised it's the wrong day and it's a non-flex ticket) 

I was wondering where would be the best place to sell it? Is it worth standing in the queue at the train station offering it to people or is that a bit weird. It cost me 40chf (I'd be happy to sell it for that) but they now cost well over 100 (I'm carsharing now)

Any help would be great! Thanks, Ed
