Nah, you just sue in Norway. Might be expensive for Amazon to defend, but that's their problem.

More specifically: Norway is part of the Brussels regime for determining jurisdiction to sue ( http://en.wikipedia.org/wiki/Brussels_Regime ). So this applies:

A consumer may bring proceedings against the other party to a contract either in the courts of the Contracting State in which that party is domiciled or in the courts of the Contracting State in which he is himself domiciled.

And no, companies can't escape it by putting a jurisdiction clause in a consumer contract. Consumer protection law trump contract terms. If Amazon want to do business in a country, they have to abide by the consumer laws of that country.

(I am not a lawyer).

That presents a bit of a problem. As digital stuff is being increasingly sold across geopolitical lines you get a situation where you have little practical recourse if you have an issue with anything you have bought.
