Taxes not charged for international orders

[Cripes]

I have a site that sells printed books and small gifts internationally, using PS 1.5.4.1.

 

In the UK books are 0% tax rated. However, we charge the usual 20% on gift items and some t-shirts.

 

Prestashop doesn't seem to allow for both taxes properly to added for all orders outside of the UK, as the combined tax rule is an average not both together. (As the items are mostly small mail order items we don't allow for the reclaiming of taxes for tourists unless they visit our shop).

 

Any ideas to add both taxes to international orders?

I'm not sure I understand what you are trying to accomplish.

 

I assume you have a tax rule that applies to all Countries (except UK) with a 20% tax rate?

What does this mean exactly?  What is the second tax?
