#3 Loyalty (5%)$72.00$3.60= $68.40
Sequential vs additive: Most retailers apply discounts sequentially — each one on the price AFTER the previous discount. So 20% + 10% sequential is NOT 30% off; it\'s 28% off ($100 → $80 → $72). Additive mode just adds the % directly (less common but simpler).

Production-grade quality

Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.
