# Promo Codes for E-commerce

**PROMO CODES FOR E-COMMERCE**

This guide explains how Promo Codes work in Barnet E-commerce, how to set them up correctly, and common reasons why a promo code may not apply as expected.

**Where Promo Codes Are Managed**

Promo Codes are created and maintained in the **Barnet Network** under:

**Online Store → E-commerce Setup → Promo Codes**

**Promo Code Setup – Field Definitions**

When creating or editing a Promo Code, you will see the following fields:

* **Code -** What customers type into the website checkout.
* **Description -** Internal name for the promotion or campaign.
* **Start/Finish Dates -** Defines the active date range for the promo.
* **Days of the Week -** Days the promo can be used (within the range).
* **Promotion Value**
  * Fixed dollar amount (e.g., $10 off), or
  * Percentage discount (e.g., 10% off)
* **Minimum Cart Value (Optional)** Sets a minimum cart subtotal (before tax) required to use the code (e.g., $100 minimum).
* **Usage Limit (Optional)** Limits how many times the promo code can be used.

**Category Groups – How They Actually Work**

**Apply Promo Code to All Items in the Store**

* **Do NOT check any Category Group boxes.**
* Leaving all boxes unchecked automatically applies the promo code to all eligible items.

**Apply Promo Code to Specific Categories Only**

* Check **only** the category group(s) you want the promo to apply to.
* The promo will apply **only** to items in those selected groups.

**Important Limitation**

Even when category groups are selected correctly:

**Promo Codes will only apply to items that are NOT marked as “On Sale.”**

Sale items are always excluded from promo discounts.

**“Use as Discount” Setting – What It Means**

Inside the Promo Codes screen, you will see an option called **“Use as Discount”** under **Other Promo** settings.

If Use as Discount is\*\* UNCHECKED *\*Not Recommended as it creates a new Category*:\*\*

* The promo code appears as a **separate negative line item** in the cart.
* The cart shows a reduced **Cart Total** after the promo is applied.
* The invoice shows the promo as a separate discount line.

If Use as Discount is\*\* CHECKED (Recommended Setting):\*\*

* The promo is applied **directly to the product price**.
* Customers see the discounted product price in the cart.
* The invoice reflects discounted item pricing instead of a separate line.

**Why a Promo Code May Not Be Working**

If a promo code is not applying, check the following:

* The item is **already on sale**
* The promo is limited to specific category groups
* The cart does not meet the **minimum value**
* The promo code has reached its **usage limit**
* The promo is outside its **active date or day range**
* The promo code was typed incorrectly by the customer

**Best Practices**

* Promo Codes are **case-sensitive** for customers when entered on the website.
* Avoid stacking **sale pricing and promo codes**—only one can apply.
* Leave category groups **unchecked** if the promo should apply store wide.
* Test promo codes with a sample order before launching a campaign.
* Clearly communicate promo rules to customers (sale exclusions, minimum spend, etc.).
