Get GasBuddy app and you can check local gas prices. Costco is always cheaper, approx. $0.10 to $0.15. Rarely more. With a tank of 20 gallons you save $2.00 to $2.50... overall.
Too much in California. Regular gas stations are competitive with Costco. That shouldn't be true.
4.35 for regular and 4.65 premium currently
