Symptoms
Product detail pages have “(incl. VAT)” and “Delivery Cost”.
Cause
Your product is set to use the “product.3m.xml.config” XML package. This package was custom-designed for a client with special requirements. It was left in the build for developers to work on if they wished, but is not really suited for general use.
Solution
To fix this, edit your product through the admin site and change the “Display Format XML Package” dropdown menu to another choice.
