Triple Discount Calculator
This calculator lets you set a cumulative discount. Each discount is calculated from the price AFTER the previous one was applied (and not from the original price). For example, if the original price was $100 and you have 20%, 10% and 15% discounts. First, we're doing $100 - 20% = $80. Then $80 - 10% = $72. Then $72 - 15% = 61.20.
