How Stacked Discounts Work
When retailers offer "20% off + extra 10% off," the discounts don't add to 30%. They're applied sequentially: first 20% off, then 10% off the reduced price. The effective total discount is less than the sum.
Tip: Most retailers apply the larger discount first. This gives you a slightly better deal than if they applied the smaller one first.
Frequently Asked Questions
How is the sale price calculated?
Original price minus 20% = $80.00. The discount is applied to the current price, not the original.
Is it better to have one 30% discount or two 15% discounts?
One 30% discount is better. Two 15% stacked discounts give you 27.75% off total, not 30%. Sequential discounts always result in a lower effective discount than adding the percentages.
