Issue: Creating product bundles for 3PL (third‑party logistics) fulfillment where the bundle shows as a single product page item (not a pop‑up), pulls inventory from individual SKUs (stock‑keeping units), and avoids duplicate size variants. Shopify Bundles worked for a two‑pack of black socks (size only) but failed for a Black & White pack with a single size variant, causing variant duplication.
Suggested solution: Profit Bundles app. It displays bundles as standalone products, deducts inventory from component SKUs, and generally works with 3PLs. Pricing note: welcome plan is free—unlimited bundles and up to 10 bundle orders/month. Support reported as responsive.
Counterpoint: One commenter argues paying $45/month (e.g., Bundle Kit) is justified if bundles are profitable, challenging the reluctance to pay for an app.
Outcome/status: The original poster thanked the Profit Bundles recommendation and appears likely to try it. No confirmed technical fix reported yet; discussion leans toward adopting Profit Bundles with awareness of free plan limits. No images or code are central to the thread.

I want to set a couple of product bundles that will be fulfilled by a 3PL. These will be individual products that will be picked by the warehouse and sent together to the customer. I have tried Shopify Bundles but it (or I) can’t seem to get it to work without doubling up on the size variants on the Product page. It works for a two pack of black socks when the only variant is size. But when I want to create a Black and White pack, with the only variant being size - I can’t get it to work.
I need
To display the product as a ‘pack’ on the products pages not a pop up
For orders to pull from the individual product SKUs and reduce this inventory
Please help with a fix or an alternative app? I don’t want to pay $45 per month for bundle kit at the minute.
I understand your requirements around creating bundles that work seamlessly with 3PL fulfillment and avoid duplicate variants on the product page.
To achieve this, I would suggest you to try the Profit Bundles app. It allows you to display bundles directly as products (not via pop-ups) and ensures that inventory is correctly deducted from the individual product SKUs. It also works smoothly with most 3PL setups.
What’s great is that you can try these features free of cost—there’s no paywall. On the welcome plan, you can create unlimited bundles and process up to 10 bundle orders per month. Plus, their support team is quite responsive.
Seen this cliche thousands of times.
You WANT a $45 app to make you money.
If a bundle app can’t give you a profit over such a low amount why are you spending any business time on this at all instead of things that are actually profitable.
3PL + bundles can be tricky - the key is whether your 3PL needs separate SKUs or can handle “virtual bundles.”
Option 1: Virtual Bundles (No new SKU) Apps like Shopify Bundles, Fast Bundle, or BundleGPT add items separately to the order but display as a bundle to customers. Your 3PL picks individual items. This is usually easiest.
Option 2: Pre-packed Bundles (New SKU) 3PL to ship a pre-packed box, you’ll need to create the bundle as a new product/SKU in their system. Then use an app to sync inventory.
Which approach depends on your 3PL’s capabilities. What 3PL are you using? Happy to give more specific advice.
Also - which products are you planning to bundle? Sometimes the fulfillment headache isn’t worth it if the bundle doesn’t have strong purchase correlation in your order data.
