In checkout e.g.

Shipping tax 18%
Tax 6%
Tax 18%

We should probably distinguish the tax on products and the shipping cost in labels

In Orders:

Subtotal(net) - total price od products(without tax)
Shipping cost - price of shipping(with tax)
Taxes - taxes of products

It is a bit confusing that the tax is already included in shipping cost and only products are taken into account in Taxes
