Frequently Asked Questions
How do I calculate a discount?+
Multiply the original price by the discount percentage divided by 100, then subtract from the original price. Example: $80 with 25% off = $80 - ($80 × 0.25) = $80 - $20 = $60.
How do double discounts work?+
Double discounts are applied sequentially, not added. A 20% + 10% discount is NOT 30% off. First apply 20% to the original, then apply 10% to the already-discounted price. The effective discount is 28%.
Is tax calculated before or after discount?+
Sales tax is calculated on the discounted price, not the original price. This means you save on tax too when buying discounted items.
