The example demonstrates an application of a Buy X Get Y discount. The example uses the sample _E-commerce Site_.

We want every [registered customer](https://docs.kentico.com/k10/managing-users/role-management.md) to get free book _Responsive Web Design_ for buying any piece of electronics from _Electronics_ department.
