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!

This app makes it way easier to manage the store. It’s simple but really effective, and the setup was super quick.

⭐️⭐️⭐️⭐️⭐️
Fantastic app with top-notch support!

I’m using XB: Sticky Add to Cart Upsell for my Shopify store, and I’m absolutely satisfied. The app offers great features to increase conversion rates and is easy to customize.

What impressed me the most was the support – I had a small issue with the German translation, and the team fixed it within a few hours! Such fast and professional service is rare.

A must-have for any store owner looking to optimize their checkout.

XB: Sticky Add to Cart Upsell is an excellent Shopify app that offers many features while being very well designed in terms of ease of use. I’ve tried several, and this is the one that convinced me the most.

I had a great conversation with Steve from the support team, who impressed me with his availability and professionalism. The result is spectacular. Thanks again!

I looked at a few cart apps on shopify and this was the only one that I saw that had everything that I needed which included an announcement, ability to add notes, tiered discounts, and upsells. I was pleasantly surprised by how easy it was to set up and it looks very professional. Will definitely make a difference in conversion. This is my biggest drop off point so I am looking forward to see the changes!

Customer service is spectacularly good, extremely attentive, and very fast. The app is really well done and has many features. I love it, I'm definitely going to use it in all my stores.

Ive tested a lot of cart apps, UpCart, Rapi, etc. but i have to say this is the best one yet. The customer support is very quick and handles every problem seamless. Victor is a great Support! Thanks

Working with Victor was an absolute pleasure. He quickly understood exactly what I needed, adapted the button functionality on my site perfectly, and went above and beyond to make sure everything worked smoothly. What stood out most was how accessible and responsive he was throughout the process – I never had to wait long for a reply or a solution. Highly recommend him if you're looking for someone reliable, talented, and easy to work with. Thanks again!
