Doh. It gets worse. I just talked to the Danish Store.
We got 2x500$ gift Cards. They can only be used one at the time.
So If I then wanted to buy a Surface Pro 2, so I don't loose the entire value of the gift codes. Then my options look like this:
Surface 2 pro 1200$ on the Danish store (without keyboard/64GB). I use one gift code, and have to pay up 900$. Thanks.
Or I can buy an old XBox 360, and 2 old games 2 times.
