Bundles MD lets merchants sell a gift set from a main product page without a separate kit product. Pick the main product, add at least one extra product, and set a percent or fixed discount. Shoppers buy the main product alone with theme Add to cart, or add the full gift set as separate cart lines. When quantities match the exact set, Shopify applies the discount at checkout. If the set is broken, the discount is withheld. Quantity deals with volume tiers are available on a single product.
