Contrary to the typical dynamic of pressuring suppliers to lower costs, Target encouraged e.l.f. to introduce a higher-priced product line ("e.l.f. Studio" at $3). This strategy aimed to increase the brand's average sales per linear foot.

While pausing sales for 6 months to rebuild, Legora framed the delay as a consequence of overwhelming demand. They put new, signed customers into a "queue," creating scarcity and social proof that inadvertently made the product even more desirable by the time it was ready.

Unlike brands that flood the market and rely on markdowns, Norwegian Wool carefully controls its distribution channels and production quantities. This ensures a high percentage of items sell at full price, creating real margins and a "fear of missing out" that drives early-season sales.

The recession acted as a tailwind for e.l.f. As consumers sought value, major competitors launched expensive drugstore lines that failed. This created a market vacuum and opened up precious retail shelf space for e.l.f. to fill.

When TikTok users started emptying Halo Glow bottles to make custom lip glosses, e.l.f.'s leadership immediately joined a TikTok Live to participate. Within one week, they launched a "do-it-yourself" kit with an empty bottle, rapidly institutionalizing the organic trend.

A feature in Glamour was contingent on product accessibility. With no retail presence, e.l.f. had to quickly build an e-commerce site, inadvertently launching a direct-to-consumer channel that became a cornerstone of their business.

A powerful marketing gimmick involves launching a very small product batch to guarantee it sells out quickly. Brands then leverage this "sold out" status in press coverage to create a perception of high demand and build hype for subsequent, larger product releases.

The Nike-Costco sneaker collaboration sold out instantly with zero press releases, ads, or official announcements. The brands leveraged secrecy to fuel online rumors, creating immense organic hype and demonstrating that for exclusive products, the most effective marketing strategy can be to say nothing at all, embodying the 'buy the rumor' principle.

Brands can strategically trigger Fear of Missing Out (FOMO) by imposing purchase limits, like 'limit 10 per customer'. Research shows this tactic is highly effective; shoppers will often buy, on average, 70% of the stated limit, even if they initially intended to buy far fewer items.
