SeatGeek, and got a reasonable deal. Of course pricing and demand went up for the conference games, but lots of season ticket holders will list tix to preconference games, especially for midweek/weeknight games.
However, I expect listed prices to be a little more this year for those types of games, and even more so next year if AJ Dybantsa signs.
Conference game tix will be much harder to buy, especially for games like KU, because anything listed for those will fetch a big big price.
