What are some good (non internet) places to trade ammo?

I was thinking of taking them to the Queen Creek gun show coming up. But idk if your allowed to bring ammo in if your not a seller. I've seen people carrying guns with a for sale sign on it, but are there rules about bringing in ammo?

Shouldn't be a problem.

This will be their second show in Queen Creek and I haven't seen any rules whatsoever with respect to person to person sales.
