You can buy at the box office at no extra cost.
in purchase at the box office there are also taxes imposed at the time of purchase
Purchased tickets last week on a Sunday of Chicago on the same day of the show for $99 each. Wasn't aware of booking fees etc. Seemed to be a flat rate for those seats in balcony. Bought tickets on same day hoping they might be cheaper but maybe buying early is the way to go.
