# Why Is only one pre-order product added to the cart?

If you're only able to add **one pre-order product** to the cart, it could be due to the following reason:

* **Old Pre-order Model with Discount or Partial Payment Enabled**\
  When using the old pre-order model **combined with Discount or Partial Payment features**, the system is limited to processing **only one pre-order product at a time**.

Additionally:

* Clicking the **Pre-order** button in this setup will **redirect customers directly to the checkout page**, bypassing the cart. This prevents multiple pre-order products from being added together.

***

> ✅ **Tip:** If you want customers to add multiple pre-order items to the cart, consider switching to the **new pre-order model** without enabling discount/partial payment features or contact support for a solution
