Looking for App: Add One Product to Cart → Automatically Discount All Other Items

[utkilts]

Hi all, I'm trying to find a Shopify app (or a workaround) that will let me do the following:

1. When one specific product (let’s call it Product A) is added to the cart,

2. I want all other products in the cart to receive an automatic discount (e.g., 15% off),

3. The discount should apply automatically, without the customer needing to enter a discount code.

I've looked into several bundle and BOGO apps, but most require the discounted items to be manually added as part of the bundle, or they can’t apply the discount broadly across the cart.

Is there any app that supports this type of trigger-based cart discount, or would this require a custom app or Shopify Functions? I’m not on Shopify Plus, so Script Editor isn’t an option.

Thanks in advance for any suggestions!

Hi @utkilts , 

Thanks for reaching out to the Shopify Community! I'm Mia from MooseDesk , your go-to Live Chat, WhatsApp and FAQ App here to help enhance your customer support experience 😊

You're absolutely right — most bundle or BOGO apps require items to be pre-grouped or don’t support dynamic, trigger-based cart-wide discounts unless you’re on Shopify Plus (which supports Scripts or Functions). Since you’re not on Plus, here are some workarounds and apps that can still help  achieve a similar experience:

1. DiscountYard – Stack Discounts

• Set up conditional cart rules (e.g., if Product A is in cart, apply discount to others)

• Supports auto discounts without codes

• Flexible targeting of products/collections based on cart triggers

2. AIOD – All‑In‑One Discount

• Supports advanced discount logic

• You can set a rule like: “If Product A is in cart, apply X% discount to all other items”

• Fully automatic, no code needed

• Works well for stores not on Plus

3. Shopacado Volume & Tiered Discounts

• Not just for volume — it can be configured with trigger products

• Might require a workaround by tagging "Product A" and setting rules for when it's detected

Most of these apps have responsive support teams, and you can often request minor customizations tailored to your store’s logic — like only discounting non-Product A items. It’s worth reaching out to them directly if the default settings don’t quite cover your needs

Moreover, as your business grows and you begin to connect with more customers, efficient communication will become even more crucial. I suggest exploring MooseDesk, a FREE Live Chat, WhatsApp & FAQ App. You can easily reach customer support via WhatsApp, ensuring immediate assistance for inquiries. Also, the widget provide multi self-Service options such as Order tracking, Translation and FAQ section empower customers to resolve common questions on their own, reducing the need for direct support.
