I want to purchase tickets directly from the box office in CASH for Get the Led out, they are $27 advance, are there fees imposed when paying in that manner?

Sometimes they are sold out

Box office fees are far less than Ticketmaster fees!! You can call the casino box office and order over the phone! They are the best

No there are no fees but expect to pay a higher price if you don't get them in advance

I dont believe the box office charges fees. But they will likely cost more on the day of the show
