Frequently Asked Questions
How does a stacked discount work (e.g. 40% off + 20% coupon)? ▼
Stacked discounts are applied sequentially, not added together. A $100 item with 40% off becomes $60; the 20% coupon is then applied to $60, making the final price $48 (a 52% total discount, not 60%).
Is sales tax calculated before or after store discounts? ▼
In most jurisdictions, sales tax is calculated on the discounted net selling price rather than the original manufacturer suggested retail price (MSRP).
