The Mathematics Behind It
How Chained Discounts Work
A highly misunderstood retail mechanic is multi-layered double discounts like `50% + 20% Off`. This does **not** mean `70%` off the original sum. It means a `50%` reduction first, followed by a `20%` reduction from the already discounted secondary amount. This results in an effective total discount of `60%`, not `70%`. Our tool natively maps that correct logic locally.
