I looked on the Tech website and I quote:
"Individual game tickets go on sale August 10th, excluding Texas A&M and Oklahoma tickets which will only be available for purchase through a mini-pack on this date. All seats for North Dakota State, Rice, and New Mexico are $35, Kansas and Kansas State $55, and if available Texas A&M and Oklahoma $95."
