The math
- Cost per unit = (case cost × cases per order + delivery fee) ÷ (units per case × cases per order).
- The cheaper supplier is the one with the lower cost per unit; 0 means they cost the same.
- Savings per order = the gap in cost per unit × the units in one order from the cheaper supplier.
