The offer converts the ergonomic chair into a high-value bundle that offsets shipping concerns by stacking a high-margin bonus and a conditioned guarantee.

- Baseline: 2.0% CVR
- MDE: 0.3%
- Metrics: Primary: Revenue per Visitor; Guardrail: Return Rate.
Next steps
- Verify the 4% return rate assumption with historical data.
- Confirm the lumbar pillow assembly does not require a separate shipping box.

About this skill
The problem
E-commerce promotions often fail because they rely on arbitrary discounts that erode margins or use fake scarcity that destroys brand trust. Merchants struggle to combine bundles, bonuses, and guarantees into a single offer that is both mathematically sound and psychologically compelling.
What it does
- Calculates total effective discount by compounding unit costs, bonus values, and projected return rates.
- Maps specific customer objections to high-leverage proof elements like social proof or authority.
- Structures margin-safe bonus stacks by maintaining a minimum 2:1 perceived-value-to-landed-cost ratio.
- Generates single-variable experiment plans to validate price anchors and bundles before scaling.
- Identifies fulfillment bottlenecks and margin floors to prevent operational collapse during high-volume sales.
Why this beats prompting it yourself
Generic prompts often hallucinate fake urgency or ignore the compounding cost of "free" bonuses and shipping. This skill enforces a strict economic audit, ensuring every claim in your marketing copy is backed by your actual unit economics and fulfillment capacity.
Use cases
- Architecting a high-ticket bundle for a product launch or seasonal promotion.
- Diagnosing an underperforming listing by re-mapping objections to proof elements.
- Transitioning from flat discounts to margin-protective bonus stacks.
- Designing a controlled A/B test for a new risk-reversal guarantee.
Known limitations
Requires specific unit economics data including landed costs and conversion rates. Does not handle inventory management, ad creative generation, or legal compliance reviews.
Requires baseline unit economics, landed costs, and fulfillment capacity limits. Does not replace legal or financial sign-off. Cannot verify scarcity claims without merchant data.
