Frequently Asked Questions
How do I calculate percent off?
Multiply the original price by the discount percentage (as a decimal), then subtract from the original. Example: $120 x 0.25 = $30 off, final price $90.
Do stacked discounts work that way?
No — a '20% off + 10% off' coupon stack applies sequentially, not as 30%. The second discount applies to the already-discounted price.
