I live in Poland and was dismayed to find out sour skittles aren't actually even sour here(missing the citric acid dust). And, I haven't been able to find any good sour candy in stores, other than import stores. (But somehow they can still devote shelves to functionally identical chocolate bars).
My bitterness aside, does your country have any good sour or spicy candy?
My favorites are Zours and Shockers, but I think they'd be essentially impossible to find here
