People no longer work 9-5 Monday to Friday , if I was a STH I would have needed to take a days holiday to go. Once the club get the go ahead to slap in another 8,000 seats the potential ticket exchange scheme goes out the window.
I think it works out roughly the same buying a ST and only going to 15 games than buying match tickets on an individual basis , so looking at it from that aspect 8 games are freebies.
