About
Sam's Club Pharmacy is the pharmacy division operating within Sam's Club warehouse membership clubs, providing prescription filling, immunizations, health screenings, and specialty pharmacy services to Sam's Club members at competitive pricing leveraging Walmart's pharmaceutical purchasing scale. Part of Walmart Inc. (NYSE: WMT), Sam's Club Pharmacy operates more than 500 pharmacy locations inside Sam's Club warehouse clubs across the United States, offering members discounted prescription pricing as part of the Sam's Club membership value proposition.\n\nSam's Club Pharmacy's competitive advantage lies in Walmart's massive pharmaceutical purchasing power — the combined Walmart/Sam's Club pharmacy network is one of the largest in the US, enabling negotiated drug pricing that can undercut traditional retail pharmacies. Members access prescriptions at Sam's Club prices with convenient access during their warehouse shopping trips. The pharmacy offers $4/$10 generic prescription pricing for common medications, mail-order options, and immunization services.\n\nIn 2025, Sam's Club Pharmacy operates within Walmart's broader health strategy — Walmart Health (primary care clinics) and Walmart+ pharmacy benefits are being integrated to create a comprehensive health services ecosystem for Walmart and Sam's Club customers. The retail pharmacy market faces structural challenges from pharmacy benefit manager (PBM) reimbursement pressure that has forced independent and chain pharmacy closures. Sam's Club Pharmacy competes with Costco Pharmacy (similar warehouse model), CVS, Walgreens, and mail-order PBM pharmacies. The 2025 strategy focuses on expanding specialty pharmacy capabilities, integrating prescription benefits with Walmart+ membership, and growing immunization and preventive health services.
NYSE: COST | $2.6B Rx revenue 2024 (11th largest US pharmacy); 19%+ prescription growth; below-market drug pricing open to non-members in most states; no PBM markup model
About
Costco Pharmacy operates as a pharmacy benefit integrated directly into Costco's warehouse membership model, offering prescription drug dispensing at significantly below-market prices by leveraging Costco's bulk purchasing power and low-margin retail philosophy. Founded as an extension of Costco Wholesale's membership warehouse business, the pharmacy operates on the principle that drug costs should be transparent and accessible, a differentiated stance in an industry dominated by opaque PBM pricing arrangements. Costco Pharmacy serves both Costco members and, in most states, non-members who can access the pharmacy counter without a warehouse membership.\n\nThe pharmacy operates across 650+ Costco warehouse locations in the United States, Puerto Rico, and internationally, offering a formulary of generic and brand-name prescription drugs at prices that often undercut major chains by 50–80%. Costco does not participate in most prescription drug insurance networks, which keeps overhead low and pricing simple — members pay a known cash price rather than navigating co-pay structures. The pharmacy also offers compounding services, pet medications, and immunizations at select locations, and integrates with Costco's optical and hearing aid departments to serve the full healthcare needs of its membership base.\n\nCostco Pharmacy is consistently ranked among the lowest-cost pharmacy options in independent drug pricing surveys, creating strong loyalty among members managing chronic conditions or high-cost specialty medications. The pharmacy benefits from Costco's 130 million+ cardholders globally, who view low-cost pharmacy access as one of the core value drivers of their membership. As PBM reform and drug pricing transparency become legislative priorities in the US, Costco's no-frills cash-pay model is increasingly viewed as a reference point for what pharmacy pricing could look like without intermediary markup layers.
