XB: Sticky Add to Cart Upsell

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.
