We ask for developers to price their game excluding any sales tax (like VAT). This means that the final price you pay is the developer’s price + sales tax. Since implementing this we’ve learned that in Europe people tend to expect VAT to be included in pricing, so we did it backwards. It’s likely we’ll change this structure in the future, but it would have a substantial impact on developer earnings so we haven’t started looking into it too deeply yet.
So until we make any changes: Although you may be paying more, the developer is also getting more.
