Carty: Cart Upsell Cart Drawer

The reviews are overwhelmingly positive, with merchants repeatedly praising the app’s ease of use, clean design, flexible customization, and ability to improve conversion-related metrics such as AOV, conversion rate, and cart abandonment. Many reviewers say the app integrates well with their theme, works smoothly on mobile and desktop, and offers useful features like add-to-cart bars, quick buy buttons, sticky bars, and mini cart functionality. Several merchants also note that the app is free or offers strong value compared with paid alternatives, which adds to the overall satisfaction. The strongest recurring praise is for customer support. Reviewers consistently describe the support team as fast, friendly, proactive, and willing to go above and beyond, including helping after hours, on weekends, and with custom code or theme-specific fixes. A smaller number of reviews mention that the app did not perfectly fit their specific needs at first, or that they needed custom modifications to make it work as desired, but even in those cases the support team was commended for trying to help quickly and effectively. Overall, the feedback suggests a high-quality app backed by exceptional service, with only minor limitations around highly specific use cases.
