Can you pay cash for a concert and where do you go besides on-line?

I want to go to the jonas Brothers concert on August 16th, but I don%26#039;t know if concerts accept cash. Are there any other places to go to pay for a concert besides using things like TicketMaster??

Gag...don%26#039;t waste your freaking money on the Jonas Sisters, really...

But, if you must, go to the arena%26#039;s box office and buy the tickets there...
