It you eat the food they offer you can definitely get it at a better price. Furthermore Costco demands a higher quality for certain products. I don’t have the source on that but read somewhere once that say the can of soup you get at a regular grocery store then compare it to Costco they have better ingredients things like higher protein for example. I also know things like protein powder were the same price but much larger at Costco. Meat is much better quality and cheaper. Their return policy is hassle free. Probably a lot more I could say about Costco.
