Costco warehouse stores do not offer money order services; we spoke with customer service representatives in Virginia, Wisconsin, Idaho, California, and Georgia to confirm that Costco does not sell or cash money orders. One Costco representative said: “We don’t do money orders at any Costco.”
A Costco membership gets you access to store locations and discounted gas at Costco gas stations. Other member services include pharmacy, vision, and travel discounts.
To see the list of places that offer money order services, see our articles: Where Can I Get a Money Order? and Where Can I Cash a Money Order? We also have more details of how money orders work in our money order FAQ.
