The specs here are a bit contrived, as it's unlikely for a calculator to have a zero percentage. However, the scenario is quite real: In shops that don't select a shipping rate automatically in the delivery step of checkout, the shipment's cost will be zero until the customer has selected a shipping rate. At this point the promotion system will happily add discounts with no amount.
