to answer your question, No. They didn't offer half season tickets, I can't remember the exact reason why but it was something to do with the season tickets being good value and not much uptake. That may change next season with a new board.
Re, next season, assuming you're an adult (physically anyway!!), it will be £350 for the town end, although you can spread cost over 9 months.
Bollocks. Thanks for that anyway. Was more interested in a half season ticket due to the fact that i'll possibly be able to attend games from January 2014. Might just take the hit and buy one just incase and let somebody else use it from August 2013 - Jan 2014!
Luke - For years Swindon have needed a Loyalty scheme for ST holders and non alike. Obviously the ST holders would get first priority but for the games like the Oxford league/Wimbledon league last season a lot of loyal fans who travel the length of the country week in week out missed out on tickets. Grade 1 ST > Grade 2 ST > Grade 3 ST > Grade 1 Non-ST and so on..
