They can still discount 20%-25% off list price and make 35-40% of list price. If Costco just tacks on 18% you could be paying 47.2% of list price. Books tend to have big margins but other grocery items are much less. Because Costco doesn't really have big sales like the grocery stores that basically have sales that sell at cost, you can sometimes find better deals at the local grocery store than Costco. But if you buy a lot at Costco, you might average out paying less for the same grocery basket. If you only buy stuff on sale at the grocery store, then Costco probably isn't that cheap. But sometimes you can't wait for a sale and just have to grab stuff.
WinCo foods is a big warehouse employee owned chain here in the PacNW. I think they're based in ID. Anyhow, they're about as cheap price wise as it gets. It's kind of a frenzied shopping experience, which I'm not fond of, and you bag your own groceries. But it's hard to beat, even for Costco, their day to day prices and you don't do memberships. But like I said, it's pretty bare bones shopping.. don't expect employees roaming around offering to assist you. The checkers there can make good money and since it's employee owned they do some ESOP thing I think.
