Frequently asked questions
How is the discounted price calculated?
We multiply the price by the discount percentage to find the saving, then subtract it. For example, 25% off 120 saves 30, giving a final price of 90.
What does stacking a second discount do?
The second discount applies to the already-reduced price, not the original. Two 20% discounts don't equal 40% off — they combine to 36% off.
What is the effective discount?
When you stack discounts, the effective discount is the total percentage you actually saved versus the original price.
