BundleCraft vs SMART Bundles App & Upsells

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.

Let shoppers bundle and save with bundle deals, product bundles, bundle kits, mix and match bundles and fixed bundle prices. Add quantity breaks, volume discounts, tiered pricing, bulk pricing, BOGO, Buy X Get Y and free gifts. Upsell and cross-sell with product add-ons, subscribe and save, a countdown timer, a sticky add to cart bar and a variant picker. Target products, collections, customer tags or cart value. Automatic discounts stack with coupons and discount codes. Fast, no-code setup.
