ModuBundle lets merchants create flexible mix-and-match product bundles from existing Shopify products and variants. Merchants can define bundle steps, choose which products and options shoppers can select, set quantities, and apply percentage discounts. The app keeps component products and variants intact for inventory and order handling, while presenting the bundle as one guided shopping experience on the storefront.
