I guess I assumed that applying a discount to certain items would be similar to applying free shipping to only certain items. Am I mistaken? Is this impossible? Or are your instructions not going to work for discounting the shipping costs for certain items. I guess it doesn't matter whether to show how much the shipping cost they are saving, although that would be nice. But as long as it discounts shipping on only those certain items and not on items that aren't free shipping, that would suffice. Would this not accomplish this?
