It would be better if the user could only enter 0.99, 1.99, 4.99, 19.99 etc, or only choose from a list of preset prices.  For some reason people love to get unique and start charging strange amounts.

Good idea.

But the following conflict: As far as I can see, all prices entered by an file author in IP.Downloads always are net amount prices. As soon as you start using different TAX/VAT rates for different countries, it will change anyway. Then the total sum (gross) will always be different according to the TAX rate used...

I already suggested, that users should only be able to enter mandatory gross prices (=total end price) during the paid download creation. Then the according TAX/VAT rate should be substracted from the gross price. After that, commission and referral fees should be calculated on basis of the net amount.

Result: then the total prices are showing the same amount to every customer, independent from where he comes from.

After that, your suggestion makes sense for everybody  

We don't have VAT in the U.S. and no sales taxes for online purchases, so nobody cares about that.

And the USA is not the only country in the world nor is everything made, made solely for US citizans, So I reckon the people outside the USA might care

Have tidied this topic slightly, lets stay on topic for this. No need to descend to insults.

From a personal point of view I do appreciate the idea of an admin selectable choice for the seller (dropdown list maybe) in some circumstances although its obviously not gong to fit all sites, the idea does have merit in itself.
