Drive deeper engagement with your product collections by rewarding customers who buy multiple items from a specific collection. The ***Buy 3 Items from a Specific Collection*** campaign is ideal for promoting seasonal ranges, product bundles, or themed collections, encouraging customers to add more items to their cart and increase their order value.
***
## How to Set Up
Log in to your Gameball Admin Dashboard.
Click **Add Reward Campaign**.
Select the **Buy 3 Items from a Specific Collection** template.
Configure your campaign's audience, rewards, and other settings.
Click **Set Live** to activate your campaign.
***
## Campaign Trigger
The campaign trigger is configured as follows:
1. **Action:** Place Order
2. **Times:** 1 *(Number of orders required with this condition)*
3. **Rule:**
* **Field:** Collection ID
* **Operator:** Repeated Value
* **Collection ID:** *Enter the target Collection ID*
* **Repeated Value Times:** 3 *(Customer must purchase 3 items from this collection)*
This template uses the standard reward campaign setup. See the [Generic Setup Guide](/product-documentation/rewards-campaigns/start-from-scratch/setup-reward-campaign) for details.

## How It Works for Customers
A customer places an order that includes **three items from the same collection**.
Gameball automatically triggers the reward.
The customer receives the reward immediately (points, discount, badge — based on your setup).
The customer is notified via the widget or email, depending on your configuration. [Learn more](/product-documentation/rewards-campaigns/start-from-scratch/setup-reward-campaign)

## Important Notes
**Same Collection Requirement**
All three items must belong to the **same configured collection** to trigger the reward.
