Should the mulch promotion continue?
Mulch Promotion Evaluation
A home-improvement retailer is currently running a seasonal promotion on bagged mulch. The promotion has 6 weeks remaining in the spring selling season.
Business Context
- Pricing Structure:
- Regular Price: $3.50 per bag
- Promotional Price: $2.00 per bag
- Variable Cost: $2.40 per bag
- Financial Impact: The promotional price results in a negative item-level contribution margin of -$0.40 per bag ($2.00 - $2.40).
- Observed Sales Trend (last 4 weeks): Weekly mulch unit sales have increased significantly from 10,000 bags to 26,000 bags.
- Management Hypotheses: Leadership believes the promotion may also lead to larger transaction baskets and increased overall store traffic.
- Potential Confounding Factors: The observed sales lift could be influenced by various external factors, including seasonality, weather patterns, competitor pricing strategies, customer stock-up behavior, or cannibalization of sales from other landscaping products.
Available Data
You have access to the following datasets:
- Store-day sales data
- Detailed transaction baskets
- Loyalty/customer identifiers (for a subset of shoppers)
- Advertising spend data
- Inventory and stockout information
- Competitor price checks
- Store region and weather data
Questions
- Based on the provided information, should the retailer continue the mulch promotion for the remaining 6 weeks of the season?
- What key metrics would you utilize to inform this decision, and why is relying solely on item-level contribution margin insufficient for a comprehensive evaluation?
- Describe your methodology for estimating the incremental impact of the promotion, distinguishing it from the raw observed sales lift.
- If leadership ultimately decides to continue the promotion despite its negative item-level contribution margin, what compelling business justifications could support such a decision?
Your recommendation should explicitly address issues related to causal inference, customer segmentation, the inherent tradeoffs between maximizing revenue and profit, and how you would effectively present a persuasive argument to business stakeholders.
