There are a specific number of tickets at each price point. The $12 tickets are sold first. When those sell out, we sell the $18 tickets. When those are gone, we move on to the $25 tickets. Here's the rub: THEY'RE ALL THE SAME. We operate a "general admission" venue, otherwise known as "first come, first served." As soon as the house opens, anyone with a ticket can enter and select any available seat. $12 ticket or $25 ticket — it's all the same.
Simply put: buy early and you'll save money!
