Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a seasonal component. Has this increase in returns coincided with any particular season or event?

Why it matters: Seasonal patterns could indicate external factors rather than product issues. Expected answer: The increase started in early summer. Impact on approach: If seasonal, we'd focus on weather-related factors or summer shopping behaviors.

• Considering product lifecycle, I'm curious about the age of returned mattresses. Are we seeing returns primarily from recent purchases or older ones?

Why it matters: This helps distinguish between potential manufacturing issues and long-term satisfaction. Expected answer: Majority of returns are within 3-6 months of purchase. Impact on approach: Recent purchases might indicate immediate quality issues, while older returns suggest durability problems.

• Thinking about customer segments, I'm wondering if the increase is uniform across all buyer types. Are we seeing more returns from first-time Kirkland mattress buyers or repeat customers?

Why it matters: This could reveal issues with customer expectations or changes in product quality. Expected answer: Increase is more pronounced among first-time buyers. Impact on approach: If first-time buyers, we'd focus on marketing messages and initial product experience.

• Considering recent changes, have there been any modifications to the mattress design, manufacturing process, or marketing strategy in the past 6 months?

Why it matters: Recent changes could directly correlate with the increase in returns. Expected answer: A new foam supplier was introduced 4 months ago. Impact on approach: This would shift our focus to supply chain and quality control processes.
