    Example session with this skill installed

    Build an offer for a $150 ergonomic chair. COGS is $45. Objection: shipping cost. Bonus: $15 lumbar pillow (costs $4). Capacity: 50/day. Floor: 40%. Traffic: 1k/day, 2% CVR.

    • Read your context and instructions
    • Compiled the ecommerce offer builder

    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.

    Risk Reversal

    • Type: "Keep the Bonus" Refund
    • Window: 30 Days
    • Condition: Must complete the 14-day ergonomic adjustment period.
    • Expected Return Cost: $6.50 (Based on 4% return rate + logistics).

    Margin & Capacity Check

    • COGS: $45.00
    • Total Offer Cost: $55.50 (COGS + Bonus + Return Cost)
    • Resulting Margin: 63% (Above 40% floor)
    • Capacity Flag: GREEN (Projected 24 orders/day vs 50/day limit)

    Experiment Plan

    Hypothesis: Adding the Lumbar Pillow bonus will increase CVR by 0.5% because it offsets the psychological friction of shipping costs.

    • Variable: Bonus inclusion (Pillow vs No Pillow)
    • Baseline: 2.0% CVR
    • MDE: 0.3%
    • Metrics: Primary: Revenue per Visitor; Guardrail: Return Rate.

    Next steps

    1. Verify the 4% return rate assumption with historical data.
    2. Confirm the lumbar pillow assembly does not require a separate shipping box.
    3. Submit the "Keep the Bonus" policy to legal for terms of service wording.

    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.
