Checkout Components app has made Shopify checkout updates and addition of elements (upsell/cross-sell, seasonal shipping notes and everything in between) a breeze. Zero dev required. Conditional, rule based warnings and alert styles, ability to swiftly add marketing campaign creative: piece of cake. Recommended for anyone from lean ecomms/digital teams to larger organisations. The robustness of the app made for an especially smooth migration to checkout extensibility (and a bug-free UAT on the way). Very much looking forward to future feature enhancements from this excellent and key addition to our tech stack.
