It's quite odd that the price for this varies depending on where in the world you tell fastspring you are (and since it isn't geo-locked it appears you can just lie about where you are to get the lowest price).

For example, while the game costs $7.20 in the USA it is £7.20 in the UK which is around $11.20. In euros it is 7.20, around $9.30.

Is this intentional? I'm kind of surprised this hasn't come up already considering nifflas is European.
