Overview

Decides which promotion should be activated given the current order context

By activated it doesn’t necessarily mean that the order will have a discount for every activated promotion. It means that the discount will be created and might eventually become eligible. The intention here is to reduce overhead. e.g. a promotion that requires item A to be eligible shouldn’t be eligible unless item A is added to the order.

It can be used as a wrapper for custom handlers as well. Different applications might have completely different requirements to make the promotions system accurate and performant. Here they can plug custom handler to activate promos as they wish once an item is added to cart
