Paid Membership Warehouse Club

📌 Background

The warehouse membership store sector in China entered an explosive growth phase in 2025. Sam's Club China surpassed 10 million paid members, with annual sales exceeding 140 billion RMB, ranking among the top globally in both membership renewal rates and average spending per capita. Brands like Costco, Hema X, and ALDI are accelerating their expansion, forming a business model centered on membership fees, driven by curated low-price selections and private labels. By 2026, this model began shifting from Tier-1 cities to Tier-2 and Tier-3 markets, with store opening rates reaching a weekly cadence, making it one of the fastest-growing segments in physical retail.

👤 Target Customers

Middle-class families and high-income consumers willing to pay an annual fee for curated quality and cost-effectiveness. Primary usage scenarios include weekly family grocery shopping, holiday stockpiling, and corporate bulk purchasing. The payers are individual consumers or families who exchange annual fees for entry access and consumption benefits.

💰 Revenue Streams

Membership fees are the primary source of profit; for example, a standard Sam's Club card costs 260 RMB/year, with membership revenue accounting for approximately 50% of total profit, locking in profitability upfront. Merchandise sales revenue relies on high-volume, low-margin strategies. Private labels like Member's Mark contribute 45% of sales despite representing only one-third of the SKU count, boosting average transaction value and enhancing profit elasticity. Ancillary service revenue, such as tire centers and optical services, further supplements overall profitability.

🧮 Cost Structure

Major expenditures include supply chain investments in private label R&D and global direct sourcing from origins, the leasing and construction of large-scale warehouse-style stores with high-standard cold chain logistics, and the operational and precision marketing costs for millions of members.

🛡️ Moat

The R&D and procurement system for private labels and exclusive products serves as a core barrier; for instance, Member's Mark contributes 45% of sales with only one-third of the total SKU count, making it difficult for competitors to replicate. A curated selection of 4,000 SKUs combined with bulk packaging improves operational efficiency, creating a price structure that low merchandise margins can cover. The high-value customer base and repurchase data filtered by the membership threshold form a bilateral positive flywheel for greater supply chain bargaining power and store growth.
