The Club are still waiting to see if they have any ticket returns themselves (the ones they give sponsors, WAGS etc) before they start to allow STHs to sell their tickets on the system - it's to protect their interests.
There comes a point in life where you realise that time has a value, and when you sum the number of hours going to and from a game via bus>train>train>game>[either leave in 75th minute or wait an extra 30 mins>train>train>bus you wonder if it's worth it.
Looks as though the Club are finding more and more vacant seats now....
I would be surprised if the Club chose to open up the Ticket Exchange for this game as they really won't want to "publish to the world" the number of STH who are willing to sell their tickets. Hopefully I'll be proven...
