# 2025-05-26: Cart Service - adding items as separate lines to a cart

## Overview

The cart service now allows adding items to cart as separate lines. This means the same product can appear in the cart multiple times, enabling you to apply external discounts or fees to individual items. To add item as a separate line, specify `keepAsSeparateLine` property in the `Adding a product to cart` request.
