Cartix Cart Discount + Upsell

We wanted an easy way to customize our cart in our store and Cartix has been an awesome option! We are very happy with the customization options for color, and alerting customers of discounts so that they don't miss out. I was also very pleased that when I reached out to the support team to inquire if they had a specific feature, they took the time to make edits to the app to include the feature we needed! We do not currently use their upsell tool.
