Frequently Asked Questions
How do stacked discounts work?
Stacked discounts apply consecutively rather than being summed. For example, 20% off followed by an extra 10% off results in an effective 28% total discount, not 30%.
Is the discount calculated before or after tax?
In retail, discounts and coupons are almost always applied to the sticker price before sales tax is calculated.
