# How to Create Product Discounts on Shopify with Atom Volume & Gift Discounts

> Create product and collection discounts in Atom Volume & Gift Discounts with clear setup steps, maxQuantity guidance, and practical examples.

## Product Discounts at a Glance

Use product discounts when you want a direct price reduction on specific products or collections.

What they are good for:

* Promoting a featured SKU
* Running category-level campaigns
* Clearing targeted inventory
* Testing pricing sensitivity with controlled exposure

## Choose the Right Product Discount Type

| Type                    | Use it when                                 | Example                                 |
| ----------------------- | ------------------------------------------- | --------------------------------------- |
| Single Product          | You want to promote one product quickly     | 20% off one featured product            |
| Collection              | You want one rule across a category         | 15% off all winter jackets              |
| Advanced Single Product | You need exclusions or purchase constraints | USD 50 off one-time purchase only       |
| Advanced Collection     | You want scale plus tighter controls        | 25% off collection with maxQuantity = 3 |

For type-specific behavior, see [Offer Types](/offers/offer-types).

## Single Product vs Collection

Use **Single Product** when control at SKU level matters.

Use **Collection** when you want easier maintenance across many products. New products added to that collection can inherit the offer automatically.

## maxQuantity and Margin Control

`maxQuantity` limits how many qualifying items can receive the discount per order.

* `-1` means unlimited discounted quantity
* Any positive number limits discounted units to that count

### Example maxQuantity behavior

Offer: `20% off Premium T-Shirt collection`, `maxQuantity = 3`

Customer cart: 5 shirts at USD 30 each

* Shirts 1-3 discounted to USD 24
* Shirts 4-5 remain USD 30
* Discount applied to 3 units only

Use this when you want to keep promotions attractive without giving away too much margin on large carts.

## Setup Create a Product Discount

<Steps>
  <Step title="Create a New Offer">
    In Atom Commerce, go to **Offers → Create New Offer**.
  </Step>

  <Step title="Choose a Product Discount Type">
    Select **Single Product**, **Collection**, **Advanced Single Product**, or **Advanced Collection**.
  </Step>

  <Step title="Set Offer Basics">
    Add an internal name, customer-facing discount name, schedule, and activation method.

    <Tip>
      Use clear names you can identify quickly in reporting, such as "Winter Coats 25%".
    </Tip>
  </Step>

  <Step title="Choose Activation Method">
    Select one:

    * **Automatic** for frictionless checkout
    * **Discount Code** for campaign-specific access
    * **Coupon Batch** for distributed one-time codes
  </Step>

  <Step title="Select Qualifiers and Targets">
    Pick products or collections that should trigger and receive the discount.
  </Step>

  <Step title="Set Discount Value">
    Configure one mode:

    * **Amount Off** (for example, USD 10 off each item)
    * **Percent Off** (for example, 20% off)
    * **Fixed Price** (for example, USD 49.99 per item)

    <Callout>
      Fixed Price applies only when the fixed price is lower than the item's current price.
    </Callout>
  </Step>

  <Step title="Configure maxQuantity and Advanced Rules">
    Set maxQuantity, exclusions, and optional constraints such as channel, budget, or fulfillment settings.
  </Step>

  <Step title="Test and Activate">
    Validate behavior across multiple cart sizes and save.
  </Step>
</Steps>

## Clear Examples

### Example 1 Single Product flash promotion

* Rule: 25% off Product A
* Use when: launch campaign or short promo window

### Example 2 Collection campaign with margin guard

* Rule: 15% off Winter Collection
* maxQuantity: 3
* Use when: you want broad reach with controlled exposure

### Example 3 Fixed-price value framing

* Rule: Any qualifying hoodie at USD 49.99
* Use when: fixed pricing is easier for customers to evaluate than percent discounts

## Best Practices

* Start with one clear objective per offer
* Prefer collection-based rules when operating at scale
* Use `maxQuantity` for margin-sensitive categories
* Keep messaging customer-friendly and specific
* Review [Offer Priority and Stacking](/offers/priority-and-stacking) when multiple offers can match the same cart

## Troubleshooting

### Discount not applying

* Confirm offer is active and in schedule
* Confirm product/collection selection is correct
* Confirm channel and fulfillment constraints allow the cart
* Check priority conflicts with other offers

### Discount amount looks off

* Verify the configured discount mode
* Verify maxQuantity behavior for larger carts
* Test mixed-price carts if using fixed-price offers

### Unexpected overlap with other offers

* Review stacking settings and priorities
* Separate high-priority campaigns into distinct time windows when possible
