Quick answer
Use a fixed kit when every shopper should get the same bundle. Use FBT when the main product stays fixed but add-ons are optional.
- Pick the offer type that matches how shoppers already buy — not the type with the most features.
- One clear primary offer per product page usually converts better than stacked widgets.
- Kitforge lets you configure coexistence when FBT, quantity breaks, and fixed kits overlap.
- Test the full mobile flow before sending paid traffic.
Quick decision
Use a fixed kit when every shopper should get the same bundle. Use FBT when the main product stays fixed but add-ons are optional.
Choose fixed kit when
- You sell a known kit: camera + lens + bag
- Gift boxes with predetermined items
- Starter routines with fixed steps
Choose the alternative when
- Hero product with optional accessories
- Shoppers may want only some add-ons
- Attach rate matters more than a single bundle SKU
Final recommendation
The right bundle type is the one that matches your catalog and buying moment. Kitforge supports fixed kits, FBT, and quantity breaks — pick the type that needs the least explanation on the product page.
If you want this kind of offer to feel native to the buying journey, Kitforge Bundles is built around that exact problem: turning related Shopify products into clearer bundle offers before the shopper reaches checkout.
FAQ
Can I use both approaches?
Usually pick one primary offer per product page to avoid shopper confusion. Kitforge coexistence settings help when you need exceptions.
Which does Kitforge support?

It is built for merchants who want product-page bundle widgets, inventory-safe checkout, live previews, and analytics — not just hidden discount rules.
