First, we asked fuel market analyst Patrick De Haan at GasBuddy, an app that finds deals, how many gallons the typical American driver buys in a year. He said 600, which works out to roughly 40 purchases of 15 gallons each. We then identified 13 Costco warehouses in metro areas that cover the continental US and compared their gas station prices to GasBuddy's average price for those local markets on the same day.

One of Costco's biggest ways to save doesn't involve setting foot inside a warehouse. The wholesale club has been selling gasoline since 1995, and many US warehouses now have pumps for members to top up. The company is even set to open its first-ever stand-alone gas station in California this year. The savings make gasoline one of the biggest ways shoppers say their annual membership fee basically pays for itself.
