Shopify Bundles doesn't update a bundle's price when a component's price changes. Kumiko Bundle Price Sync detects the change and recalculates the bundle price with the policy you choose: match the component total, keep a discount rate, or keep a fixed discount. Every update is logged and can be undone. Nothing changes until you opt in — the default is notify-only, so you first see which bundles drifted and by how much. Requires Shopify's Bundles app; updates prices only, never bundle contents.

• Detects component price changes and updates the bundle price automatically
• Four policies: match total, keep discount rate, keep fixed discount, notify only
• Set a policy per bundle, plus a store-wide default
• Drift dashboard shows every bundle that's out of sync and by how much
• Full history with one-click undo; a safety threshold blocks large jumps
