Fly: Bundles & Quantity Breaks vs XB: Post Purchase Upsellfor Shopify (2026)

Fly: Bundles & Quantity Breaks and XB: Post Purchase Upsell both aim to increase Average Order Value (AOV) for Shopify merchants, but they approach the problem from different angles. Fly focuses on pre-purchase strategies, encouraging customers to add more items to their cart through bundles, quantity breaks, and upsells presented *before* the checkout process. This app targets merchants who want to proactively influence purchasing decisions and incentivize larger orders through volume discounts and attractive bundle offers directly on product pages or within the cart. XB: Post Purchase Upsell, on the other hand, specializes in post-purchase upsells. This app is designed for merchants who want to capture additional revenue *after* a customer has already completed their initial purchase. It leverages one-click upsells, presenting targeted offers to customers immediately after checkout without requiring them to re-enter their payment information. This app appeals to merchants seeking to maximize the value of each transaction by presenting highly relevant offers based on the initial purchase and customer attributes. While both apps aim to boost AOV, their timing and approach differ significantly, targeting different stages of the customer journey.
