Providing attractive discounts on weekends, festivals, first-order, etc., is one of the best tactics to boost sales quickly for the Magento 2 stores. The store owner can create coupon codes for offering discounts and promote them on various advertising mediums.

Coupon codes are generated and applied with Cart Price Rules – which allows applying discounts in the shopping cart based on a set of conditions and coupon codes. Discounts are applicable only when a customer enters a valid coupon code on the shopping cart page.
