Yeh there prices are steep if you get something you don't like. As I suggested what I found was going there in person and trying like 30 plus juices over a few hours relaxing in their lounge and cool drink helped me find what works for me a there shop, though my suggestions are meaningless as everyone's tastes differ.
I live 25 minutes door to door from them so I pick up as I agree shipping is kind of steep as well.
