Quick answer
Quantity break widgets default to hiding when a fixed kit inline purchase option is on the same product page. Change coexistence to show_below or show_above if tiered pricing should still appear.
- QB hides by default when inline fixed kit is present.
- show_below places tiers under the kit widget.
- One QB offer renders per PDP.
- Avoid competing discount stories on one SKU.
Decision guide
If customers usually buy single units in bulk, prioritize quantity breaks. If they buy curated kits, prioritize fixed kit inline and keep QB hidden.
Final recommendation
Hidden quantity breaks often reflect coexistence defaults — not a bug. Choose the primary offer type for each hero SKU.
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 QB apply to kit components?
Quantity breaks target eligible products you select — typically the hero SKU, not the bundle parent.
