Frequently asked questions
How do I calculate 25% off?
Multiply the price by 0.75. $80 at 25% off is $60.
Is 20% off plus an extra 20% off the same as 40% off?
No, it's 36% off. The extra 20% applies to the already-discounted price: $100 → $80 → $64.
Is sales tax charged on the original or sale price?
On the price you actually pay after store discounts. Manufacturer coupons are taxed differently in some states.
