If you buy tickets at the oracle box office do you avoid all those fees that drives the price of a ticket up like 20 dollars?

Yes

Nope

No they will allways get you some how. I was there fri night at a event the tickets wherw 15$ i was shocked heres the messed up part 40$ parking fee and i think another 60$ for somthing else i cant rember i was upset by it. Also eat before you go for 2 hot dogs and 2 sodas 37.65! And after the show theres far better hot dogs with grilled onions etc for only 5$

Probably

Yes, but you risk not getting a ticket, if it is sold out
