shopify bundle app discount stacking with codes
Bundle apps plus percentage codes can double-count the deal. Reproduce both paths, then lock combine rules before BFCM-scale spend.
The actual problem
Bundle apps plus promo codes double-discount and destroy kit margin on paid orders.
Do this
- Test bundle PDP with and without sitewide codes.
- Disable combine on either the bundle or the code — pick one lever.
- Review last 50 bundle orders for effective discount %.
- Scan for other stacking paths before BFCM-style events.
