musicfan or anyone, I am a new fan and am wondering if the San Diego concert on Aug. 31 at Humphrey's will sell out same day, or if I can wait till Sunday morning to buy tickets?
Don't have an answer for that, but I will bet that the seat selection is better the sooner you get the tickets. The GK website has a pre-sale code of SAVOR listed.
As a side note, I should add, it might be worthwhile contacting the venue box office directly. Tickets available through ticketmaster are not always the same as what is offered through the venue directly. I have gotten better seats by going directly through the box office. They are also able to tell you what seats are sold, and what has been blocked off (to be sold at a later date).
