Detailed Analysis

Proposed Solution

A front-end widget and checkout UI extension that tracks cart contents in real time, groups items in threes, highlights the cheapest free item, and auto-applies the discount when thresholds are met.

Target Audience

Merchants running B2G1 or mix-and-match promotions seeking higher AOV and clearer on-site messaging.

Competitive Landscape

Vitals, ReConvert, Monster Cart Upsell, Honeycomb Upsell, UpliftHero

Implementation Notes

Build a JavaScript widget using the Storefront or Cart Ajax API to mirror backend rules and compute groups of three client-side; display progress bars, badges, and the projected free item on PDP/cart; integrate with Checkout UI Extensions to show savings at checkout; support Liquid section and headless setups; include analytics for engagement and AOV lift; provide fallback messaging if the discount engine is not installed and deep-link to install it.
