Free Shipping Recalculation recomputes the free shipping threshold (set in Admin->Modules->Shipping->Free Shipping Options or through Admin->Modules->Order Totals>Shipping) to be adjusted up for order total discounts that apply to the cart. So if your normal free shipping kicks in at $100, but the customer has a $25 Better Together discount, the Free Shipping threshold is raised to $125. Please note that coupon support for the Free Shipping Recalculation is extra. This mod does not work with changes to the standard Zen Cart checkout, such as One Page Checkout or Fast and Easy Checkout. This is an installed price. After you order, I will contact you for a list of your discounts plus the FTP and Zen Admin credentials for your cart.
