My Two Brows includes a free sample pack with every size and style in a customer's first purchase. This incentivizes the initial sale, educates the customer on the product range, ensures they find their perfect fit for future orders, and ultimately increases customer satisfaction and repeat business.

Don't try to force customers to adopt new behaviors, like a boot-buyer purchasing sandals. Instead, focus on encouraging them to buy a second pair, a newer model, or an upgraded version of the product they already love. This audience-focused approach builds on existing loyalty and is far more effective.

Instead of trying to reach inaccessible celebrities directly, UGG strategically targeted their stylists. By sending free boots to a list of 400 Hollywood stylists, the brand efficiently seeded its product into celebrity culture, leading to organic placements in magazines.

When US sales were nonexistent, UGG's founder persevered by recalling the product's massive popularity in Australia. This belief—that the problem was his execution, not the product—was a critical motivator to push through early failures and self-doubt.

A UPS store owner required each employee to comp one customer's order daily. This empowered employees, delighted random customers, and led staff to engage more deeply with every customer to decide who most 'deserved' the daily gift, improving the experience for all.

To overcome skepticism about takeout cups, Kroc didn't argue. He offered a free supply of cups and lids to one store for a month. This zero-risk trial allowed the concept to prove itself, turning a reluctant manager into an enthusiastic advocate and creating a self-expanding account.

Coca-Cola's first-ever manufacturer's coupon did more than attract customers. It drove foot traffic for retailers, making them eager partners, and gave independent salesmen a free value-add for their own customers, creating a powerful, multi-sided growth engine.

Daniel Lubetzky initially had an $800 sampling budget, viewing it as a cost. He realized gifting bars generated immediate ROI through word-of-mouth. He scaled the budget from $800 to $20 million, which became the primary driver of Kind's explosive growth, reframing a cost center into a growth engine.

A UPS store owner mandated that each employee comp one customer's purchase (up to $30) daily. This simple rule empowered employees, forced them to engage deeply with every customer to find a worthy recipient, and transformed a transactional service into a delightful experience.
