Norway is very, very expensive... I tihnk Oslo is the most expensive place in the world to live. however I get a lot of stuff from Germany, and use the adage 'buy once, buy right' , so I don't waste a lot of money.
In terms of livestock, the advantage I have is locally we get fish and inverts (fresh and salt) from source, meaning indonesia, s america, rather than thro' a wholesaler. It means a store here has a far larger 'selection, range' than a US store that orders thro' a wholesaler, and will usually have a limited list. It does mean what they have at any time is total potluck tho, so most everything I get is a special order. Also, for example, they might have 10 different apistogramma for sale, then none for the next 6 months as there are no more deliveries form Columbia, peru for a while. There is normally only one Red Sea delivery every 6 months to a year.
