Buy European

Fritz cola is the only decent European cola I see sold in Estonia. It's ridiculously expensive in that you can buy a two liter Coca Cola or Pepsi for the price of a 330ml Fritz. It's OK if you're alone and only want the one small bottle, but when you've gotta share, it's about as much as a home-cooked family meal. For a literocola.

Admittedly, the taste of Fritz Cola has way more nuance than Coca Cola. And I'm more of a Fanta man and yay, Jaffa is pretty much as good and just as cheap as American Fanta.

One of the local grocery stores also has a decent store-brand Sprite alternative so that covers most of the bases, just would sometimes like to have a cheaper good European cola available.
