Is there a way to farm money pre-Elite Four? I decided with my best friend to challenge the Elite Four at the same time, but we are able to meet in Friday. I really would like to do things in Pokemon while waiting. I already collected five hearts to all my bros in Amie and I have five stars in every Amie minigame in every difficulity level, so now I thought I could get some money to buy clothes. I am really poor because I put all my money on healing items. I also will fix my dex too while waiting.

tl;dr: Any way to farm money in Y before Elite Four? Amie is already fully done. Filling Dex atm.
