Auto Add Free Gift to cart

Increase your conversions with this lightweight, easy-to-install script that automatically adds a free gift to the cart when a qualifying product is added — no app required.

How It Works:

When a customer adds any product from a specified product list, the script checks their cart and automatically adds your chosen free gift. If the qualifying item is removed, the free gift is automatically removed too — keeping your offer clean and seamless.

Features:

• Works with Shopify’s native “Buy X Get Y” discount setup
  
• No third-party apps or subscriptions required
  
• Completely customisable:
  
• Change the qualifying product handles
  
• Set your own free gift product
  
• Modify logic to suit any product combination
  
• Works in any theme with a cart drawer or standard cart page

Includes:

• Clean, well-commented JavaScript code
  
• Easy step-by-step installation guide video
  
• Ongoing support for theme integration

Perfect for stores running bundle promotions, seasonal offers, or just wanting to reward loyal customers — all without cluttering your store with unnecessary apps.
