I currently use ShopSite through Start Logic. I have been trying to offer free shipping to customers who select one specific item in my store. ShopSite give all opportunity to allow free shipping on the specific item selected, but does not provide an option for "Free Shipping" on the entire order, "If this one item is selected". It appears to be a simple change to the code to offer free shipping on the item selected, or the entire order. Please tell me if there is a work around, or if you are planning to offer this in the future. I have thought about using the Add-On option in the Shipping screen, but have not had any success with it to date.
By the way, Start Logic simply claims that that function is not possible.
