This coupon from the Kansas City Convention and Visitors Association will get you a $10 discount on any available ticket to the 2012 Tour of Gymnastics Champions, which is coming to the Sprint Center in Kansas City on October 18, 2012.
The coupon says it’s good at the Sprint Center box office or online. I couldn’t verify that it will work online without entering all my credit card information, which I wasn’t willing to do because I’m not planning to go. There’s also a $10.50 convenience fee for buying online, so it’s cheaper to get your tickets at the box office. If you do order online, the promo code is CHOPPER.
