The Costco Wholesale Story
Since 1983, Costco has redefined the retail experience by putting members first. What started as a single warehouse in Seattle has grown into a global network of 827 warehouses serving over 133.8 million cardholders across 14 countries. Our mission remains unchanged: deliver exceptional value through honest pricing, quality products, and an unwavering commitment to customer satisfaction.
Built on a Simple Principle
Co-founder Jim Sinegal established a rule that still guides every decision we make: never mark up any item more than 14% above wholesale cost. This isn’t marketing—it’s our operating philosophy. While other retailers chase maximum margins, we chase maximum trust. That 14% cap means the savings we negotiate from suppliers go directly to your cart, not our bottom line.
More Than a Warehouse
Costco isn’t just about bulk buying. We’re a destination for families and businesses seeking quality across every category:
4,847+ unique items per warehouse span from farm-fresh Honeycrisp apples to Dyson cordless vacuums, from professional-grade tools to stylish furniture collections. Our buyers curate selections that balance everyday essentials with premium finds, all backed by our legendary satisfaction guarantee.
27% average savings versus traditional grocery stores prove our model works. Members don’t sacrifice quality for price—they get both. Our private-label Kirkland Signature line demonstrates this perfectly, sourcing from top-tier manufacturers while eliminating brand-markup layers.
310,000 employees worldwide staff our warehouses, tire centers, optical departments, and hearing aid centers. They’re trained to deliver efficient service whether you’re checking out on a busy Saturday or fitting new eyeglasses at Costco Optical.
Quality You Can Trust
Our commitment extends beyond price tags. Kirkland Signature products meet or exceed name-brand specifications because we partner directly with recognized manufacturers and enforce rigorous quality benchmarks. USDA Organic certifications, independent lab testing, and third-party verification back up our sourcing claims across categories from coffee to batteries.
Our return policy reflects this confidence: if a product doesn’t meet your expectations, bring it back—no receipt gymnastics, no restocking fees, no fine print.
Serving Every Need
From cutting-edge electronics and energy-efficient appliances to automotive care, professional healthcare services, and premium pet nutrition, Costco serves every aspect of modern life. Our tire centers provide major brands with complimentary rotation services. Our optical and hearing aid centers deliver professional care at a fraction of retail prices. Our photo center preserves your precious memories affordably.
