In China's coffee market, price wars are no longer surprising. What is more interesting is the way Luckin Coffee often chooses to discount: instead of permanently lowering prices across the ordering interface, it sells limited-time coupons through livestream rooms. To consumers, this adds friction. To the business, the friction is the point.
Hidden price discrimination
A direct listed-price cut gives the same discount to everyone. That is costly because it also discounts users who would have paid the standard price. Livestream coupons create a screening mechanism: price-sensitive users are willing to spend time watching, buying, and redeeming coupons; time-sensitive users may still order at ordinary prices because the coupon process feels inconvenient.
This turns time cost into a market segmentation tool. The same coffee can effectively be sold at different prices without formally breaking the official menu price.
Prepayment and liquidity
A normal discount transaction happens when the drink is purchased. Coupon selling changes the timing: consumers pay first and consume later. When large volumes of coupons are sold in a livestream, the company receives cash before delivering the product.
That prepayment works like low-cost liquidity. It can support traffic acquisition, store expansion, procurement bargaining, and operational turnover. In a market where scale and speed matter, cash received earlier is strategically valuable.
Sunk cost and repurchase lock-in
Once consumers have unused coupons in their account, the future choice set changes. Passing another coffee brand may trigger a simple thought: the Luckin coupon is already paid for, and not using it before expiry would feel like a loss.
This is not just a one-off sale. Coupon inventory in the consumer's wallet becomes a behavioural nudge that pulls future visits toward Luckin and away from substitutes.
Protecting the price anchor
The most strategic reason may be price-anchor protection. If the menu constantly displays a permanent low price, consumers may internalise that number as the fair price. Later price increases would feel like a loss or betrayal.
Livestream coupons frame the low price as a special event benefit. The official price remains visible, while the discount feels conditional, temporary, and earned. This protects brand pricing power and leaves room for future adjustment.
Commercial takeaway
Luckin's livestream coupon strategy is not merely a sales channel. It is a combined mechanism of price discrimination, liquidity management, behavioural lock-in, and brand defence. The company spends more on content, traffic, and operations, but it may save far more by protecting margin and consumer psychology.
For consumers, the lesson is equally useful: when a limited-time coupon appears attractive, the real question is not only how much money is saved today, but whether future choice has already been quietly pre-committed.
