You can't you only get one. The only way to get more is to cheat or trade.
You can get them from the lottory or Professer Elm but you can not buy master balls.
Buy an action replay from gamestop
you cant buy master balls in any Pokemon game so far. you only get one from prof. elm afta you have got all 8 johto badges
you don't you only get one per game from prof. elm, after you beat Claire
I do belive there won't be that kind of cheat, but a smart, but long way is to buy a Pokemon pearl, or diamond, then cheating on that game, then trading and having those Pokemon have master balls.
U can't buy fast balls but u can buy quick balls or maybe get them out of apricorns
no
From what I know, You can't BUY master balls in Pokemon.
buy an action replay for about 20 dollars and u can have infinite masterballs;) this also works in soul silver but the grand prize in the Pokemon lottery corner in the radio tower first floor is a master ball
Answer:You cant buy fast balls, but you can have Kurt make them by giving him any number of Wht Apricorns in Azalea Town.
You cannot BUY master balls. You only get 1 master ball in the game.
you can only get one masterball in every Pokemon game
