Buy X Get Y With Multiple Discount Tiers

A Buy X Get Y campaign allows you to offer quantity-based promotions that cross-sell different items to encourage larger purchases. When customers buy a required quantity of eligible items (X), they automatically unlock a different reward product (Y) for free or at a discount.

For example:

Buy a T-Shirt (X), Get a Hat (Y) Free
Buy 2 Pairs of Shoes (X), Get 1 Pack of Socks (Y) with 50% Off

This type of campaign is ideal for driving cross-sell conversions, introducing customers to new product lines, clearing specific excess inventory, and raising Average Order Value (AOV).

Before You Start

Before creating your campaign, make sure:

You know which items or collections customers need to buy (X).
You know which cross-sell items or collections customers will receive as a reward (Y).
You have planned your purchase tiers, reward quantities, and discount values.
Your Shopify theme has the app properly installed and enabled.

Step 1: Create the campaign

Go to: Campaigns -> Create campaign -> Buy X Get Y.

Step 2: Configure Campaign Info

Campaign Status

Enable or disable the campaign using the Campaign status toggle.

Active: The campaign is live and available to customers storefront-wide.
Inactive: The campaign is saved as a draft and won't be displayed on your storefront.

Campaign Name

Enter a campaign name for internal reference (e.g., T-Shirt Buys get Free Hat Campaign). This name is only visible within the app dashboard.

Discount Label

Enter the text that customers will see when the discount is applied (e.g., Gift with Purchase). This text will appear in the cart and during checkout.

Active Dates

Schedule when your Buy X Get X campaign starts and ends.

You can configure:

Step 3: Configure Campaign Rules

Customer Buys (X)

Choose which products qualify as the trigger requirement for the offer.

Specific products: Apply the buy requirement only to selected items.
Specific collections: Apply to all products within selected collections.
All collections: Apply across your entire product catalog.

How Purchases Qualify for the Offer

Combine quantities across selected items: The quantities of all eligible "X" products in the cart are added together to unlock the reward tier.
Require quantity from the same item: The required trigger quantity must come entirely from a single, individual line-item variant.

Customer Gets (Y)

Choose what separate product(s) the customer receives as their reward:

Different product: Select this option so the reward is a specific product or a selection from a collection (Y) that differs from the item variant being purchased.
Press the Select products button to add the designated gift product(s) or collection(s) to the campaign.

Configure Buy X Get Y Tiers

For each tier, configure the exact progression rules:

Buy quantity: Minimum quantity of X items the customer must buy.
Get quantity: The quantity of Y reward items unlocked for the customer.
Reward type: Choose between Percentage or other markdown settings.
Reward value: Enter the discount value applied to the reward item Y (e.g., enter 100% for a free item).

Note: You can click + Add new tier to create progressive levels (e.g., Tier 1: Buy 1 X Get 1 Y, Tier 2: Buy 2 X Get 2 Y).

Check Apply multiple times based on quantity if you want the gift count to multiply based on growing cart sizes.

Gift Limit

Toggle the Gift limit option to control how many gifts a single customer can claim. When turned OFF, customers can claim the gift continuously as long as they meet the purchase requirements.

Step 4: Advanced Settings

Step 6: Save and Test Your Campaign

Before activating, verify the following checklist:

Campaign status is toggled to Active.
Eligible Customer buys products that match your X criteria.
Customer gets is configured to the correct separate reward product Y with your tier discounts verified.
Presentation widgets (Popup, Cart drawer, etc.) are enabled and stylized to match your theme.

Troubleshooting

The gift selection popup does not appear: Check that the campaign is Active, the customer has added the exact required quantity of eligible items (X) to their cart, the popup display option is checked, and your theme app embed is enabled.
Customers are getting multiple gifts incorrectly: Review your Gift limit toggle and check if Apply multiple times based on quantity is turned on or off depending on your promotional goals.
The Buy X Get Y deal cannot be combined with another discount: Verify your Advanced settings -> Combinations and ensure you have checked the boxes for Product, Order, or Shipping discounts.
