XB: Cart Upsell Cart Drawer

This cart drawer app is excellent—it looks clean and professional on both mobile and desktop. It includes many important features and is very simple to use and customize. The support team is also great. Highly recommended!

I rarely leave reviews, but the XB Sticky Add To Cart & Upsell app deserves all the praise. First of all — it’s completely free, which is almost unbelievable given how feature-packed it is. From the smooth sticky add-to-cart bar to the powerful upsell options, this app delivers everything you’d expect from a paid tool, and more!

Installation was effortless, the UI is clean and intuitive, and it integrates perfectly with my theme. I noticed an immediate boost in conversion rate after enabling it — customers love the seamless shopping experience.

And I can’t say enough about the customer service — they are truly amazing! Super responsive, friendly, and always willing to help with custom tweaks or questions. It’s rare to find such high-quality support on a free app.

If you’re running a Shopify store and want to boost sales and improve UX without spending a dime, look no further. XB Sticky Add To Cart & Upsell is an absolute game-changer.

Very nice app! The point is that it's still free and very suitable for small and medium sellers! I had some problems with the app and communicated with Andrewg in customer service, and after 1 hour of communication, he helped me to solve the problem. Thanks to the developer and customer service Andrewg!
