If you’re targeting weekday games you can get in the door vs. any team for <$40. Weekend games, especially in Gampel, goes for over $100. It really depends on schedule.
The highest priced game last year, Creighton on a Saturday at Gampel, went for over $100. St John’s on a Friday night in Gampel was less, about $50 to get in the door last minute.
Baylor, at Gampel on a Tuesday, tickets plummeted to $15-20 an hour before the tip. The XL schedule was trash so any game was $10-20 if you waited. The year before on a Saturday vs. Marquette (both teams ranked Top 5) the prices did not move under $175.
My advice: if you have a crew of 2-4 just buy seasons it’s 10x less stressful. If you fly solo you’ll save money buying game by game.
