How to Set Up “Buy X, Get Y” on Shopify: Two Paths to Success Now that you’ve seen how real stores make “Buy X, Get Y” offers work, let’s walk through how to set it up in your own store. You can start with Shopify’s built-in tools or use an app like AOV.ai Free Gifts BOGO & BXGY if you want more control and a smoother experience. Method 1: Using Shopify’s Built-In Tools Shopify supports a “Buy X, Get Y” discount type that you can create in your admin dashboard. How to set it up: Go to Discounts in your Shopify admin. Click Create discount, then select Buy X, Get Y. Define the “Buy X” condition: which products or collections, and how many items or what minimum spend. Define the “Get Y” condition: which item the customer will receive, and how many. Optionally, set a limit on how many times this discount can be used in one order. Publish with start and end dates, and explain the offer clearly on your store so shoppers understand how it works. What works well: It’s free and already built into Shopify. For simple campaigns like “Buy one, get one free,” it’s a good starting point. What to keep in mind: The free item must be added manually by the customer. Shopify does not add it automatically. The discount only applies when both the qualifying and free products are in the cart. It doesn’t apply on the post-purchase or thank-you page. The built-in version lacks advanced tools like auto-add, smart targeting, and customizable design controls Method 2: Using AOV.ai Free Gift for a Seamless Experience If you want your “Buy X, Get Y” offer to look clean and feel effortless, AOV.ai Free Gifts BOGO & BXGY makes it simple.

Each card includes a short description and example, so you can pick the structure that fits your business best. Here’s how to set it up: Open the AOV.ai Free Gift & BXGY app in Shopify. Select the campaign type, for example Buy X Get Y. Choose the products or collections that qualify for the offer. Set your conditions such as minimum spend, quantity, or customer group. Preview the design and messaging so it matches your brand style. Activate your campaign. When shoppers meet the conditions, the free gift appears instantly in their cart. What works well: The interface is clear and easy to use. Each campaign type is visual, so you can create offers in minutes without technical setup. The design stays on-brand. The widget automatically uses your store’s fonts and colors, keeping everything consistent and modern. Built-in AI helps you choose the best gift or spending threshold based on your data, making each campaign more strategic. Rules are flexible.

It’s ideal for brands that want both beauty and performance in their promotions. The setup takes only a few extra minutes, and the result is a free-gift experience that feels polished, personal, and completely aligned with your brand identity. Small Tip for Both Methods Whatever method you choose, make sure to test your offer before going live. Try adding different combinations of products to your own cart. Check that the gift appears correctly and that your messaging looks clear. Keep your checkout steps simple so the reward feels smooth and instant. Takeaway Both paths work. Shopify’s built-in tool is great for quick tests and simple campaigns.
