JUICER and Bio stores in Porec? (Zagreb)

I'm moving to Croatia on September 9th and I need to find a place to buy a good (but not expensive!) juicer to juice veggies and fruits (not a blender). Any ideas where I can find one?

And also, I need things like Almond Butter, Avocado, kale, pure egg whites (bottled, not fresh if possible), flax seeds, gluten free wheat bread - can you get things like that in Porec or Pula, or would it have to be Zagreb or somewhere bigger than Porec?

I'm asking because coming from Czech, there's very little access to the above things and it's so frustrating! I've never been to Cro before so I have no idea where to get this stuff (and I don;t have a car so it will have to be near public transport!)

Thank you so much!

P.S. Hubby and I are looking to meet and chat with any English-speakers (of any nationality!) in the Porec, Fuskulin, Pula area! Drop us a line - thank you!!!
