not even when you add a product to your cart…
you might also want to inform visitors (in the footer f.e.) if prices wether or not include taxes and shipping
Taxes are different from region to region.
That’s why ghi does not require you to pay any taxes.
Mind if you import it to a different country (let’s say Europe) you will have to pay customs over the product(s) if the sum is higher then 50 euros.
I am not sure, but I believe the customs for the Netherlands are 9%, because they see it as a computer product in the computer products range.
Little side info here, but I agree that this should be printed somewhere
