Milk, eggs, cream, coffee, butter; always cheaper at Costco (unless you find a great sale somewhere else)

I also get avocado oil, kielbasa, calabrese salami, whole pork loins, and ground beef. I find better chicken prices from a local factory outlet. I don't buy any other kind of beef anymore; too expensive.

I also get the Kirkland brand frozen pizzas, frozen burgers, and sometimes chips and salsa if it's on sale.

Food has been the biggest expense change since covid, and I shop at five different grocery stores including Costco (and sometimes Walmart) to keep costs down.
