Understanding Double Discounts
Double discounts, also known as successive discounts, occur when multiple percentage discounts are applied one after another. Understanding how these discounts work is crucial for making informed purchasing decisions and maximizing your savings.
How Double Discounts Work
- Sequential Application: Each discount is applied to the already discounted price, not the original price
- Compound Effect: The total discount is less than the sum of individual discounts
- Order Independence: The order of applying discounts doesn't affect the final price
- Diminishing Returns: Additional discounts have less impact on the final price
