Frequently Asked Questions
Multiply the original price by the discount percentage (as a decimal), then subtract from the original price. For 20% off $50: $50 × 0.20 = $10 discount, so sale price is $40.
Not necessarily. Compare the final prices. 30% off $100 ($70 final) is better than 50% off $200 ($100 final) if you want to spend less.
Divide the sale price by (1 - discount%/100). If something is $80 after 20% off: $80 ÷ 0.80 = $100 original price.
For stacked discounts, apply each one sequentially. 20% off then 10% off is not 30% off – it's 20% off, then 10% off the reduced price.
