If I go to the sprint box office to buy tickets,will I still have to pay the additional fees that I have to pay to buy tickets online??

You only pay convenience fee online. To avoid extra fees go to box office.

Open hours

No.

No extra fees.

Some places do charge the fee some don't. You just need to call them find out

No I do not believe that is their policy if you live a distance away you might want to call and ask but I'm almost positive no extra fees

Not the I believe. Those are online service fees
