I am trying to create a Radio Button List or Drop Down list in 'Product Modifiers' (under Shared Choices) for extra White Glove Shipping cost. So far, we have Free Shipping on all orders. When I change 'Shipping Adjustment' and you try to add product to the shopping cart, it doesn’t reflect shipping cost on the website. I need to change 'Price Adjustment' instead… in order for me to add that extra shipping cost... So, extra White Glove Shipping cost just adds to the product price but I want to have it as an extra shipping cost. Any idea how to solve this issue?
