Costco gas is famously a loss leader, typically running 15 to 20 cents below surrounding stations.
Is this true? I always assumed that Costco just had better deals/longer horizon commitments so it could undercut local stations. Maybe they even own a refinery just to maintain the best margin.
I started screenshotting my local Costco warehouse gas prices weekly since the week prior to Trump's inauguration, mostly so my Trump supporting brother inlaw couldn't just spew his Fox brainwashing on me without me hitting back with this data.
I've been tracking every fuel purchase I've made for 12 years now across 5 or 6 different cars. Not sure what I'll ever do with that information, but I suppose it may come in handy for a political argument.
The only times I’ve seen it relatively empty were during bad storms.
That said, it’s not an hour wait. Around 20 minutes is average, but I rarely fill up there since I value my time much more than that.
