Just come back from Brettas Supermarket and this is on offer at e1.35 a bottle.
I have some, cooling, in the fridge, waiting for the "Eggy Verdict"
Probably local supermarkets are selling this as well,around the same price, but e3.50 at a Bar, or Taverna/ Hotel for a 2% volume Ginger Beer sounds like a good deal to me.
Also, maybe take a tour around the beer factory. I'm told, at the end of the tour you get to buy the special ales/barley wine/ginger beer at a knock down price. Ex-visitors may know more.
Cheers
