A sourcing strategy of splitting a bundled product's components — e.g. the core product, the box/packaging, and add-on items — across separate, specialized suppliers rather than one all-in-one factory. A competitor would need to identify and coordinate the same combination of suppliers to replicate the exact bundle, which raises the cost and time of copying the listing, functioning as a low-cost competitive moat.
Complements Bundling, Color Psychology & Surprise-Gift Differentiation: the bundle is the differentiator on the customer side, and multi-supplier sourcing is what makes that same bundle harder to clone on the supply side.
Apply: split sourcing across multiple specialized suppliers for a bundled product's different components so competitors can't easily copy the full combination in one move.
