Costco vs Walmart 2026: Which Retailer Offers Better Value?

Costco offers better unit pricing on most products and exceptional quality for members who buy in bulk — but requires a $65/year membership fee and stocks fewer items. Walmart's everyday low prices, no membership requirement, and vast selection make it the default for most households. Costco wins for families buying staples in volume. Walmart wins for smaller households, convenience, and one-stop shopping.
