# Combinations

## Overview

Shopify has rules about which discounts can be combined. Advanced Free Shipping discounts are "shipping discounts" and have specific combination rules.

## Shopify's Combination Rules

In the "Combinations" section of each discount, you can choose:

* **Product discounts** - Can this combine with product discounts?
* **Order discounts** - Can this combine with order discounts?
* **Shipping discounts** - Can this combine with other shipping discounts?

## Default Behavior

By default, Advanced Free Shipping shipping discounts:

* ✓ Combine with product discounts
* ✓ Combine with order discounts
* ✗ Do NOT combine with other shipping discounts

{% hint style="info" %}
Only ONE shipping discount can apply per order. If multiple qualify, Shopify applies the best one for the customer.
{% endhint %}

## How Shopify Chooses

When multiple shipping discounts qualify:

1. Shopify calculates the final shipping cost with each discount
2. Applies whichever gives the customer the lowest shipping cost
3. Only that discount is used

**Example**: Customer qualifies for both:

* Discount A: 50% off shipping ($10 → $5)
* Discount B: $7 off shipping ($10 → $3)

Shopify applies Discount B ($3 is better than $5).

## Common Scenarios

<details>

<summary>Product Sale + Free Shipping</summary>

**Customer uses 20% off product code + free shipping**

* Product discount: -20% on products
* Shipping discount: Free shipping (if cart ≥ $50)

These combine! Customer gets both discounts.

</details>

<details>

<summary>Multiple Shipping Discounts</summary>

**Customer qualifies for VIP and cart value discounts**

* Discount 1: VIP → Free shipping
* Discount 2: Cart ≥ $100 → Free shipping

Both are free, so either one applies (same result).

</details>

<details>

<summary>Tiered Discounts</summary>

**Customer qualifies for multiple tiers**

* Discount 1: Cart ≥ $30 → 25% off shipping
* Discount 2: Cart ≥ $50 → 50% off shipping
* Discount 3: Cart ≥ $75 → Free shipping

Shopify applies the best one (free shipping if cart is $75+).

</details>

## Best Practices

{% hint style="info" %}
Create tiered discounts without worry - Shopify automatically applies the best one.
{% endhint %}

{% hint style="info" %}
Leave combinations enabled for product/order discounts - customers appreciate stacking.
{% endhint %}

{% hint style="info" %}
Don't try to combine multiple shipping discounts - Shopify only allows one.
{% endhint %}

## Automatic vs Code Discounts

* **Automatic discounts** - Apply automatically at checkout
* **Code discounts** - Require customer to enter a code

{% hint style="warning" %}
Customers can only use ONE discount code at checkout. If they enter a shipping code, they can't also enter a product code.
{% endhint %}

**Recommendation**: Use automatic shipping discounts so customers can still enter product discount codes.

## Tips

* Use automatic discounts for shipping (no code needed)
* Reserve discount codes for product/order discounts
* This lets customers benefit from both without choosing
* Test combinations in Test Mode to verify behavior
