I went to Ticketmaster through the SU Alum presale link today. The sale started at 3:00PM and I was logged in and ready at 2:59PM.
The "best available" seats for either the UNC or Dook game within 30 seconds of them going on sale were for section 322 Row X at $50 each. Section 322 is across from the football end zone on the opposite side of the dome.
I was surprised that better tickets were not available on a "pre-sale" before the general public tickets go on sale tomorrow. On the other hand, it means there will likely be 35,000+ for these games.
I did score tickets for the Villanova game in section 103.
