# Discount classes
Discount classes are only available on Unified Discount Engine (v2) and not on Discount Engine (v1) and other functions offered by Dollarlabs. This is based on the unified discounts architecture detailed by [Shopify](https://shopify.dev/docs/api/functions/latest/discount?example=create-combined-multi-type-discounts).
This functionality basically enables brands to do product, order and shipping discounts all through a single function.
> Apply three discount types in one Function: 10% off the entire order, 20% off the most expensive item in the cart, and free shipping on all deliveries.
One such example is shared above which is easy to configure with Dollarlabs: Ultimate Discounts.
