I prefer Costco meat selection. In my area anyways, Sam's sells choice meat ay the same price Costco sells prime .
But they're two different animals.
Sam's is for those who like to buy name brand in bulk. Costco are for those who like to buy a lot of brands you don't see else where. Specifically their Kirkland brand which they tout as a premium brand.
Incant really speak to the truth of that or not because I buy only very limited things at Costco.
Just like Sam's, there aren't too many things you can get there cheaper than somewhere else when speaking in terms of unit costs. You just have the opportunity to buy it in bulk. But there are savings to be had, especially if you're a good comparison shopper and know how to bang them on their sales
