I don't have any codes for you, but is there anyway for you to attend on opening night? It will be here in KC the next week, and opening night tickets are only $10. We have done this for the past 3 years, because the seats are MUCH better than what we want to spend--for weekend shows. We are in the 16th row of a HUGE arena (Sprint Center). The tickets would be $38 if we went a different night.
Also, we drive to the arena to purchase the tickets instead of going through Ticketmaster. Saves us about $6 per ticket in fees.
