There is a one-day special sale on PAC-12 tournament seats: $12/session for the semi-final and final games. If you mean to go and have not already bought an all-session pass, go to this Ticketmaster page.
As usual you need to allow Flash to run and turn off ad-blocking (if you have it on). Then click a session and the seat map will eventually appear, and it looks as if reserved seats in several decent sections are available at the discount price.
The sale ends at 10pm tonight, Monday December 12.
