Quick answer
When multiple KitForge offers target one product, priority (lower number first) determines order. The storefront API returns at most one FBT and one quantity break per PDP after sorting and coexistence filtering.
- Lower priority number wins sort order.
- Only one FBT and one QB per page maximum.
- Coexistence can hide offers after sorting.
- Avoid multiple active offers on the same trigger without a plan.
Operational practice
Document which offer owns each hero SKU. Overlapping campaigns create silent suppression — the lower-priority offer never renders.
- One primary offer per hero PDP
- Use priority for seasonal overrides
- Pause old offers instead of stacking
Final recommendation
Treat priority as campaign ownership. Overlapping offers without priority discipline looks like broken widgets.
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 show two fixed kits on one page?
Inline fixed kit is typically one purchase option block. Multiple standalone products can exist but inline mode is one widget context per component PDP.
