I found it in Vancouver, BC Canada...

There's this smoked meat shop that sells imported goods, they have 1 Litres of"Lemon", "Orange", some Blue colour with some foreign name and 1.5 litre of some flavour called "Exotic".

They're imported from Yugoslavia I'm guessing as it says Beograd on the bottles a lot, I just bought my first bottle of lemon and it's in the fridge.

they cost $2 US a bottle.
