At the amphitheater, only on the day of the event. In advance, you can buy them at the OneCenter Mon-Fri 10am-6pm and Saturday 9am-1pm.
See the below answers for the correct information. I didn't want to spend the time typing information that was already entered that answered the question correctly. I'm a busy guy after all and can't just sit around typing things that are, at the end of the day, meaningless and do not benefit the overall reason the original questioner posted a question. Hope this helps and that you enjoy whatever show you are getting tickets for.
