Bundle Flow helps you sell more per order with quantity breaks, fixed bundles, Buy X Get Y, mix & match, and cart upsells. Offers appear automatically below the buy buttons on the products you target—no theme editing and no IDs to copy. Discounts apply automatically at checkout via Shopify Functions, with optional free-shipping and free-gift tiers. A live preview lets you style the widget to match your brand, and analytics show real, paid-order revenue—not just add-to-cart guesses.

• Quantity breaks, fixed bundles, BXGY & mix-and-match—auto-placed, no code
• Cart & product upsells with shipping and gift tiers
• Real-purchase analytics: revenue attributed from paid orders, not add-to-cart
