I've just realised that with 'TaxInclusive' switched on, the [total-cost] is
now exactly the same whether the user should being paying tax or not.

e.g. I have tax (VAT) set up for the countries in the EU, so shouldn't the
sales tax that is already in the product prices be deducted from the
[total-cost] for anyone outside the EU? At the moment their [salestax] shows
as '0' although it is still in all the prices.

I've got a feeling that I'm missing something again here??

Any help would be appreciated.
