I received an email at 10:05 am. Email has a presale code specifically for your season ticket account. The presell code is your Allvols account # so you can likely log into Ticketmaster without the email for the concert on Sunday and look for the season ticket presell offer, put your code in and then wait in line. I logged in at 10:50 with a queue of 600 people. Queue cleared quickly. Plenty of availability when I purchased two tickets at 11:30. Call the fund office at 865-974-1218 or the ticket office if you didn't get an email or can't use your account number to unlock the offer. I have had problems before getting their emails. In the email, they also foreshadowed a potential second concert to be announced for Friday before based on demand. I'm guessing they wouldn't have put that out unless it's a lock to happen. Just a guess.
