1. Decision: Case B (bundle-first)

Only 27.3% of orders are single-item, so BXGY (which needs a second item to trigger) would hit a minority and waste placement. The store already multi-items (median 2).,and broadly one product-type per order (93.8%) — the right lever is rewarding people to add compatible pieces of the SAME family (Zipster swaddle + Shortie + Kids PJ) via a built-bundle, anchored by the currently live Zipster+Kids bundle. Keep Free Gift as-the-second-layer above the shipping+multi-order threshold.

Free-rider at tier1 (3 pieces) is an est.45.9% of ALL orders already hold 3+ items — over Son's 30% hard gate, and mostly rewards people buying multi-piece anyway (dead money).. Tier1 should start at 4 pieces to sit under the gate (27.7%)and keep reach meaningful.

3. Free Gift candidates

Cheapest in-stock giftable SKUs, cheap enough to hold margin,and on-brief for a baby/kids brand:

Gift candidatePrice
Bodysuit Viva con AguaEUR7.9
Cuddle Cloth Lovey SlothEUR8.9
Bamboo Bandana BibEUR9.9
Ribbed Bamboo LeggingsEUR9.9
Zig Zag Large Muslin BlanketEUR14.9

Native AOV is EUR79.5 and free-shipping kicks at EUR75. Run the gift threshold ABOVE the native AOV — suggest EUR90+, keeps qualifying share below ~25% so free-rider stays within the 30% gate.

4. Third-party upsell/checkout apps

No third-party cart/checkout upsell apps are mounted. Only Upnova embed (upezFlows present, upez-frontend script) plus Klaviyo, review.io, langshop, in-site search are loaded. Upnova owns the entire cart upsell surface. Clean.

Nursing Wear cross-sellBundle Builder secondFlexible 2/4 pcs, EUR15 off mid-tier. Breastfeeding Wear collection only.BOTC (Recommendation)
Keep the live Recommendation BOTC flow(5454). It excludes Breastfeeding Wear, so it does not cannibalise the nursing inner-bundle. Good as designed.

Free-rider = share of qualifying orders that would hit the offer anyway. Reach = share of shoppers exposed. Numbers from confirmed 2,000-order ShopifyQL sample, Jun-Sep 2026. Live-tier free-rider estimates use the whole-store items-per-order distribution, may overstate for bundle-eligible-only, directionally solid.
