BundleCraft lets customers build their own bundle: pick a main product, add matching items, and the discount grows automatically. Bundles merge into one discounted line at checkout via Shopify Functions. Includes per-product personalization (engraving, gift notes), a full bundle builder section plus a compact upsell block next to your Add to cart button, an appearance editor with live preview, variant filtering, and support for theme and app cart drawers.
