Why stacked discounts don't just add
🧠
Each discount applies to the price after the previous one, not the original price. $100 at 20% off is $80. An extra 10% off that $80 is $72 — a 28% total discount, not 30%.
💵
Tax is calculated on the final discounted price in most states, applied after all discounts.
