I want to be able to offer free shipping on all products ordered if, when the customer reaches the checkout, the total order amount in their cart is ?50/$75/Euro75 or above. If the order total is below this amount, then a fixed shipping fee will apply - depending on location zones.
This may be a basic query but I'm new to oscommerce and I've been rooting around trying to find whether this is possible...if anyone could help I'd be incredibly grateful....
