Can I purchase my tickets at the copernicus center ahead of time,until the concert date or only online?

I always buy my tickets online in advance since some concerts sell out fast

Our BOX OFFICE HOURS: 2 hours before each event OR Saturdays → 3 to 5 pm OR Sundays → 1 to 3 pm Also, some Promoters sell their events tickets at local physical locations. Details are on each individual event's page on our website: https://copernicuscenter.org/

You can only buy tickets ahead of time online and at the box office the day of the event.
