Stack multiple discounts and coupons to find the final price.
Stacked discounts are sequential, not additive: 20% then 10% is not 30% but roughly 28%. Each percentage is taken from the price left after the prior discount. Retailers apply coupons one after another, so stacking never reaches the arithmetic sum of the percentages.
