I read a margin breakdown on every big box store in consumer reports and Costco was the lowest margin store there was. They make most of their money on the subscriptions.
There are also some items (beer for instance) that are drastically lower in price versus the competition. So much so that you can make your membership fee back in a couple of trips.
But yes, admittedly they do not have 100% unbelievable deals.








Of course you do dude, you believe in the invisible handjob of the market.
