There are few things here that are more expensive than in Iceland.
No I can't remember anything. :)

Just kidding. I remember one thing. When you're in the supermarket and need a bag for your purchases. The plastic bags are more expensive here but people here can also buy reusable bag that is even more expensive but, as the name suggests, can be used again and agin.
Gasoline is almost exactly the same price, it might be 10 cents higher or lower from day to day.
The refund for plastic bottles is higher here. If I buy 1.5 liter bottle of water I pay 52 cents for the water and 25 cents for refund.
To buy a house has much more costs included ,which I will come to again at a later time.
