Frequently asked questions
Is 20% + 10% the same as 30%?
No. They apply one after the other, so the real discount is 28%.
Can I use more than two discounts?
Two are built in — that covers nearly every coupon-plus-sale case.
Which discount is applied first?
The first discount comes off the list price, then the second applies to that reduced price.
