I have one way ticket for Stansted Express from Liverpool street station to Stansted Airport. I no long need it and sell it for 10 gbp. The ticket is open and valid till 19 Jan 2012. The regular single ticket is 21.50 gbp.
If you are interested, please contact me by message. I can hand it either Liverpool Street or Moorgate after 6PM on weekday.
Chrs, Hal
