Frequently Asked Questions

Key information regarding our discount and savings calculator.

When you apply a store discount (e.g. 30% off) plus a coupon (e.g. 15% off), the coupon is applied to the already discounted price, not the original price. For example, $100 with 30% off is $70, and 15% off $70 is $59.50 (an effective 40.5% discount, not 45%).

Sales tax is calculated on the final negotiated or discounted sale price, rather than the original manufacturer price, ensuring your calculated tax and total checkout price are accurate.
