How do you get like 250 berries of one kind for the berry shop to buy contest accessories?
Easiest way is to grow them. There are berry growing locations all over sinnoh. I've been asked to make a map of them, but I'm scared of such a daunting task, lol. Instead, I'll give you the list of locations.
