https://www.costco.com/ is the official digital platform of Costco Wholesale—one of the world’s largest membership-only
warehouse retailers. Founded on the principle of
“bulk purchasing at low prices”, it serves individuals, families, and small businesses, offering a curated mix of groceries, electronics, home goods, and exclusive services. Membership is required to shop, with fees funding Costco’s ability to keep prices competitive and quality high.
Its core strength lies in membership value + bulk convenience, with standout tools:
- Membership Tiers: Two main options—Gold Star (basic, for individuals/families) and Executive (premium, with 2% annual cashback on qualified purchases, plus extra perks like travel discounts).
- Bulk & Exclusive Offerings: Focuses on large-quantity items (e.g., 24-packs of snacks, 5-gallon laundry detergent) for cost savings. Also features Kirkland Signature (Costco’s private label), known for premium quality at lower prices than national brands.
- Omnichannel Shopping:
- Online Ordering: Shop bulk goods, electronics, and furniture online; choose “Warehouse Pickup” (free, for in-stock items) or “Delivery” (fee-based, for groceries/household goods).
- In-Store Integration: Check warehouse inventory, view in-club exclusive deals, and schedule services (e.g., tire installation) via the site before visiting a physical location.
- Value-Added Services: Includes optical (eyeglasses/contacts), pharmacy (prescription refills), tire centers, travel booking (flights/hotels), and photo printing—all with member-only pricing.
- Become a Member: Sign up for Gold Star or Executive membership online (fees apply) to unlock shopping access.
- Browse & Shop: Navigate categories (e.g., “Groceries,” “Electronics,” “Travel”) or search for bulk items. Filter by “Warehouse Pickup Eligible” to save on delivery.
- Choose Fulfillment: At checkout, select pickup (at a nearby warehouse) or delivery. Executive members can apply cashback rewards to orders.
- Access Services: Use the “Services” tab to book travel, schedule tire installation, or refill prescriptions—linking all transactions to your membership.
- Large Families: Buy bulk groceries (e.g., cereal, meat) to reduce frequent shopping trips and lower per-unit costs.
- Small Businesses: Stock up on office supplies, breakroom snacks, or retail inventory at wholesale prices.
- Executive Members: Maximize 2% cashback on big purchases (e.g., electronics, furniture) and use travel services for discounted vacations.
