CartStar Slide Cart & Upsell

The reviews are overwhelmingly positive. Users praise the app for being easy to set up and manage, with a customizable cart drawer and a polished sliding cart experience. A major highlight is the post-purchase upsell feature, which reviewers say works well and has already helped increase average order value (AOV) by adding extra products to orders. The app is also appreciated for providing useful data inside the app, helping merchants see its impact clearly. Support is another strong point mentioned in both reviews. Customers describe the support team as fast, responsive, and willing to implement requested features very quickly, even within the same day or less than an hour. There are no notable negative comments in these reviews, though the feedback suggests the app’s value is especially tied to its upsell functionality, customization options, and responsive support.
