Many small sellers default to blunt discounts and lose margin. This episode opens with a vivid before/after vignette: a weekend pop-up that added a $6 curated add-on to a $24 bestseller and saw conversion hold while AOV rose 25% and margin per transaction rose 8 points after fulfillment costs. We then walk a pragmatic routine: pick safe bundle archetypes, capture only consented micro-signals, score candidates in a spreadsheet, and run a 21-day suggest-only pilot that protects margin. You’ll get concrete thresholds (block any automated bundle projecting <20% margin), operational defaults (personalization retention = 7 days; hashed signals via HMAC-SHA256), and immediate deployables: a starter spreadsheet, three checkout copy snippets, and a 21-day rollout checklist at apexblue.com/micro-bundle-starter. The episode balances a founder story, sheet-first recipes, a live role-play, and a short pilot plan so listeners can implement a low-friction test this week.
