Clean, flexible, and exactly what the Shopify cart needed. Really impressed with how much control CartFlex gives you over cart add-ons without needing a developer. Setup was straightforward, the interface is intuitive, and it just works. If you're looking to increase AOV through smart cart upsells, this is the tool. Highly recommend.
