After their launch video went viral and they immediately sold out of razors, Dollar Shave Club kept sales open. They transparently informed new customers of a shipping delay but allowed them to continue placing orders. This captured massive demand that would have otherwise been lost.

When Daniel Lubetzky saw zero sales at Walmart, he assumed the product was a failure. He later realized it often meant the product was stuck in the backroom and never made it to shelves. This highlights the critical difference between a product problem and a logistics problem in CPG.

Labeling a product 'Sold Out' instead of 'Out of Stock' or 'Unavailable' reduces customer irritation by 15%. 'Sold Out' implies popularity and high demand (social proof), whereas 'Out of Stock' suggests logistical failure and company ineptitude.

Lindsay Carter's most impactful early decision was placing a second purchase order before knowing if the first would succeed.

To avoid the operational chaos of viral success, Shelter Skin deliberately caps production to match what they can manufacture and ship themselves. This prevents them from overselling and allows for sustainable, bootstrapped growth, even if it means frustrating some customers with temporary stockouts.

During post-COVID supply chain disruptions, Simple Mills viewed the chaos as an opportunity. While competitors struggled with an 80% fill rate for retailer orders, Simple Mills invested to maintain 96%. This reliability built immense retailer trust and ensured their product was always on the shelf, allowing them to capture competitor market share.
