The Opportunity

A lightweight tool that auto-injects a coupon field and apply button into the Dawn cart with rollback and step-by-step instructions. Uses discount links to pass the code to checkout and optionally shows an estimated savings banner.

"Non-technical merchants on Dawn want a simple, supported way to add a coupon input to the cart without manual Liquid edits that are fragile or theme-update-hostile."

Detailed Analysis

Proposed Solution

A guided installer that adds a Liquid snippet and minimal JS via a theme app extension, persists the coupon as a cart attribute, and applies it at checkout using discount URL parameters while showing an ‘estimated savings’ message where feasible.

Target Audience

Small to mid-sized merchants on Dawn (and similar OS 2.0 themes) who want a quick DIY solution without custom development.

Competitive Landscape

Theme snippet packs, DIY forum code tutorials, General popup/discount widgets

Implementation Notes

Provide a Theme App Extension block that renders a coupon input with minimal CSS for Dawn cart page/drawer. Save input to cart attributes and display an ‘applied’ state. On checkout CTA click, append ?discount={{code}} to the checkout URL. Optionally call an App Proxy that mirrors lines into a Storefront API cart to estimate savings and display an approximate discount banner (no hard subtotal replacement). Include a one-click installer, rollback, and theme update detection. Keep JS lightweight, avoid Liquid core edits, and expose styling controls in the app UI.
