So got a Sam's Club card cause the gas lines are much shorter than Costco. But surprise, the service is worst (well, $45 vs $60 a year for membership). Found a location with gas, but somehow Google Maps says it is closed. The website doesn't mention that, even lists the price of gas that day for the location.
Call in to speak to someone in the store, press 0, hold for 3 minutes then it disconnects. Try again, 5 minutes. Try the tire department. Same thing. Finally press a random department (turns out it is bakery) and speak to someone, who confirms gas station is closed.
I guess you get what you pay for.
