Things seemed to be pretty comparable to what you pay at the Cell to me.
The only thing that was a lot cheaper was the parking. At TEP, it's 3 bucks, at Hi-Corbett Field the parking was free (I was shocked).
Besides that, you've got your $6 margaritas and $4 cokes, pretty much on par with what you'd pay at a regular game. I didn't check the beer prices because I usually don't drink beer.
