Interesting read. But you can't consider sales tax "revenue" or "cost". Neither you nor Valve pays the revenue tax, the customer does. I always thought you enter the amount of $ and Valve adds the tax. Would make much more sense if sales tax is excluded everywhere. But I guess that would be confusing for customers. But AFAIK Microsoft does it this way, at least in the US.
