Promotion Calculation Logic: 1. Under Single Promotion: If Cart ≥ Threshold: Final Cost = Cart - Discount Otherwise: Final Cost = Cart 2. Under Multiple Promotions: Apply the tier (Threshold) met by Cart value 3. Under Optimal Purchase Plan: Simulate and compare: Net Cost = (Cart + Additions) - Tier Discount Pick Option with Minimum Net Cost.
