Post offices and banks exchange major foreign currencies and accept all travellers' cheques.
ATMs are widespread and all major credit cards are widely accepted.
Tipping is increasingly common in Norway. Wait staff are often paid derisory wages on the assumption that tips will boost their salaries, so think twice about leaving a bare table at meal's end. Taxi drivers also expect a small tip. Bargaining for services or goods is not a usual practice. We encourage you to verify any critical information with the relevant authorities before you travel.
