If you’re searching for a powerful and easy-to-use upsell app for Shopify, look no further than Fox Upsell & Cross Sell. I’ve been running my store for several years and have tested almost every major upsell app available on the Shopify App Store. Most of them are either too complicated, too expensive, or cause performance issues. Fox Upsell & Cross Sell, however, is a total game changer. The setup process is straightforward — within minutes, I was able to create product page upsells. The design options are beautiful, and everything looks native to Shopify’s modern design standards. In terms of performance, the app is lightweight and fast. I didn’t experience any delay or flickering on my pages. My store’s average order value increased by 18% in just two weeks after implementing a few simple upsell rules. That’s a huge result for such an affordable app. The customer support deserves five stars as well. They answered my questions in less than an hour and even provided step-by-step guidance with screenshots. I wish every app on Shopify had this level of support and quality. I genuinely recommend Fox Upsell & Cross Sell to all Shopify store owners — whether you’re just starting out or managing a high-traffic store. It’s reliable, intuitive, and will definitely help you boost your sales.

Fox Upsell & Cross Sell is a hidden gem among Shopify apps. I’ve tried several upsell apps before, but none of them were as customizable and lightweight as this one. The interface is clean and intuitive, and setting up offers takes just a few minutes. You can target products, collections, or even specific customer behaviors — it’s very powerful. What really sets this app apart is the support team. They went above and beyond to help me adjust the design to fit my store’s branding perfectly. Their communication was quick, professional, and friendly. I really appreciate developers who care about both functionality and user experience. I’ve seen a noticeable increase in upsell conversions since using this app. It’s easily worth more than its price.
