How do I create a discount that only works if a specific product is in the cart?

Question

I'm looking to create a more strategic discount approach for my e-commerce store where customers can only receive a promotional offer if they have a specific product in their cart. This could help me drive sales for particular items, incentivize purchases of slow-moving inventory, or create bundled promotions. I want to understand the technical implementation, best practices, and potential pitfalls of creating such a conditional discount strategy. What are the most effective ways to set up product-specific cart discounts?

Discounts That Only Work When a Specific Product Is in Cart

Product-conditional discounts are useful for cross-sell promotions, bundle incentives, and upsell offers - the discount activates when the customer adds a specific anchor product. Shopify supports this natively through product-restricted automatic discounts, with more complex logic available through Plus.

Native Shopify Setup

For a discount that applies to specific products when they are in cart:
1. Create an Automatic discount
2. Set discount type (% off, fixed amount, free shipping)
3. Under Applies to, select Specific products and choose your anchor product
4. The discount applies to that product when it appears in any cart

Limitation: Shopify's native automatic discounts apply TO the specified product - they do not conditionally activate only when a different product is present. True conditional logic (if product A is in cart, discount product B) requires Shopify Functions or a third-party app.

Common Product-Conditional Discount Scenarios

Scenario	Solution
Buy foundation, get primer at discount	Buy X Get Y discount (foundation X, primer Y at 50% off)
Discount accessories when device in cart	Shopify Functions or discount app with conditional logic
Bundle: product A + B at combined discount	Create a bundle product or collection discount

Growth Suite Cross-Sell

Growth Suite's Frequently Bought Together surfaces complementary products at a discounted bundle price when specific items are in the cart - delivering the product-conditional discount experience through a recommendation widget rather than requiring custom discount logic.
