# Unified Discount Engine (v2)

Discount engine (v2) is a huge improvement over our initial (v1) implementation, bringing in support for 

1. Cart groups 
2. Nested conditional logics
3. Derived variables from cart groups
4. Target cart groups
5. Quantity based discount limit 
6. Disbursing fixed amount across eligable line items
7. Custom discount presentation

Here's a quick and easy way to visualise how the new engine works, with the logic explained as simple flow charts

Here's also an example configuration for better understanding of the concept.

***

{% hint style="info" %}
Discount engine v2 is currently stable and will be available on all plans.
{% endhint %}

{% hint style="success" %}
You can also set up a single function to do more than just a single discount type by choosing the necessary discount classes in the function.
{% endhint %}
