Frequently Asked Questions
How do I calculate discount amount?+
Multiply original price by discount rate in decimal form.
How do stacked discounts work?+
Apply sequentially, not by adding rates directly, because each applies to updated price.

Usually yes, depending on jurisdiction and product category rules.
Why is final price not matching store display?+
Store rounding rules, coupon stacking limits, and taxable base differences can vary.

Percent-off scales with price, while fixed amount-off is constant regardless of base price.

Discounts reduce revenue and may compress margin if not priced into strategy.
