Slingshots Australia review for UpCart—Cart Drawer Cart Upsell

June 25, 2024

10/10 - Not only is this app fantastic and highly customizable - the staff will go above and beyond for anything you need. I use this app on all my stores and would never use anything else. The in-cart upsell has made a significant increase in my store's revenue and average order value. Particularly I would like to mention Mark, his attitude is 10/10 and he has helped me out in many ways. This company really does go above and beyond
