Fly: Bundles & Quantity Breaks vs Upcart—Cart Drawer Cart Upsellfor Shopify (2026)
Fly: Bundles & Quantity Breaks and Upcart—Cart Drawer Cart Upsell are both Shopify apps aimed at increasing Average Order Value (AOV) through upselling and cross-selling, but they approach the problem from different angles. Fly focuses on product bundles, quantity breaks, and volume discounts directly integrated into the product page and checkout flow. It emphasizes turning small carts into larger ones through fixed bundles, BOGO offers, and frequently bought together suggestions. Upcart, on the other hand, concentrates on enhancing the cart drawer experience with customized designs and in-cart upsells, rewards, and discounts to reduce cart abandonment. It strives to make the cart itself a more engaging and persuasive element of the shopping journey.
