Poke-Balls in coliseum

[PkmnRedFan]

Um..I am having trouble trying to find the poke-Balls in pokemon colliseum
The girl that follows you every where she keeps on sayign I have to go to the poke mart to get poke-Balls
But them when I go to the mart the guy has no poke-Balls
So where do I get them then?

go to the mart and go upstairs there's a guy who'll tell you that they dont sell pokeballs here and then go to the outskirt stand and talk to the big guy in their he will give five free and start selling pokeballs

Yes, you need to go to the train-like building where you start, that guy sells PokéBalls.
