Buy X Get Y (BXGY) offers are powerful promotional tools that encourage customers to purchase more by rewarding them with a discounted or free product when specific conditions are met.

With the Volume Discount Functions app, you can create flexible BXGY offers using different product and collection combinations.

This guide walks you through creating a Buy X Get Y offer step by step.

Available Offer Combinations

The app supports four different BXGY combinations, allowing you to tailor promotions to your strategy.

1. Product + Product

Description:
Customers buy a specific product (X) and receive another specific product (Y) either free or at a discount.

Example:
Buy Product A → Get Product B Free

This option is ideal for pairing complementary products or promoting slower-moving inventory.

2. Collection + Collection

Description:
Customers buy any product from one collection (X) and receive any product from the same or a different collection (Y) for free or at a discount.

Example:
Buy any product from Collection X → Get any product from Collection Y at 20% off

This is useful for category-wide promotions or seasonal campaigns.

3. Product + Collection

Description:
Customers buy a specific product (X) and receive any product from a selected collection (Y) for free or at a discount.

Example:
Buy Product A → Get any product from Collection B Free

This works well when you want to promote accessories or add-ons related to a flagship product.

4. Collection + Product

Description:
Customers buy any product from a specific collection (X) and receive a specific product (Y) for free or at a discount.

Example:
Buy any product from Collection X → Get Product Y at $10 off

This is ideal for gifting a featured product with broader purchases.

How to Create a Buy X Get Y Offer

1. Create a New Offer

• Go to the Offers page
  
  

• Click Add new
  
  

• Select Buy X Get Y
  
  

You’ll be redirected to the BXGY configuration screen.

2. Select Your Combination Type

Choose the combination structure that fits your promotion strategy:

• Product + Product
  
  

• Collection + Collection
  
  

• Product + Collection
  
  

• Collection + Product
  
  

Your selection determines how you will assign X (required purchase) and Y (reward product).

3. Assign X and Y Products

Next, define:

• X group – The product(s) or collection(s) customers must add to the cart
  
  

• Y group – The product(s) or collection(s) that will receive the discount
  
  

Important:
 The discount will only apply when both X and Y conditions are satisfied in the cart.

You can:

• Select individual products
  
  

• Select collections
  
  

• Define required quantities (if applicable)
  

4. Set the Discount for Y

Choose how the Y products will be rewarded:

Percentage Discount

Example: 20% off Y products

Fixed Amount Discount

Example: $10 off Y product

Free Product

Example: Get Y product completely free

The discount will always be applied to the Y group once all BXGY conditions are met.
