One of the coolest things offered by Ohio State to all students here (including MAcc) is its D-tix service. This service provides discounted tickets to different events. Some of these events include baseball (both MLB and Triple A), soccer, concerts, and even NFL tickets. A great example of this is the USA vs. Mexico World Cup Qualifier. Tickets for the match, which I attempted to purchase, were a minimum of $50 but D-tix was selling the same ticket for $25. Unlike most tickets, these tickets were lottery based, not first come first serve. Sadly, for me, I was unsuccessful both in the originally lottery for US Soccer as well as the D-tix lottery.
One tip: be aware of the line for the bigger shows. They are long and you need to get there early!
In addition, to the tickets, D-tix also offered discounted tickets to many of the tourist sites around Columbus as well as $25 dollar gift cards for $10 to some of the best restaurants in Columbus. You are only able to purchase 2 per semester but these are just some of the small ways you can enjoy Columbus without killing your wallet!
