Having a Costco membership is one of the most sought-after steps for those who live or shop in the United States. The reason is clear: low prices for volume, well-regarded private-label products, cheaper gas, and exclusive services. Here's a guide with everything you need to know to become a member in 2026 and enjoy the best prices and benefits.

For many shoppers, Costco functions as an all-in-one store.

Costco also sells travel, with packages, hotels, and exclusive benefits that extend its offering far beyond traditional shopping.
