Regarding VAT calculation:

Our shop system is geo sensitive. 

This means: 

You will see the correct price that you have to pay, depending on the country of delivery. 

1. For exports outside the European Union (USA, Canada, Switzerland, Asia.......) you will see the prices with VAT excluded. The shop system still says "VAT included" but it is calculated with 0%. 

2. If you are accessing our site from a country within the European Union, but outside Germany, you will see the price including VAT of your country.
