Martha Stewart hams and Hormel thick sliced microwave bacon. It's great for quick
BLTs and to wrap around a filet mignon before grilling. No raw bacon when the steak's done.
I love their dried blueberries, etc. I love the Kirkland brand salted mixed nuts, not too salty. I also love the Marcona almonds. I think I got that suggestion from someone here. I gave a can to my neighbor and now she has me buy them for her everytime I go.
I've always been happy with the meat I buy there. I like their beef flank for stirfries and have bought whole beef tenderloins.
Their papertowels are my favorite brand. I also buy the big rolls of plastic wrap, I think it's the strech-tite with the Kirkland brand on it now.
Their butter is very good, I buy the unsalted and keep it in the freezer. They have a package of 6 demi baguettes that are so good. We use both their big bottles of Extra-virgin olive oil, for cooking and the smaller bottle labeled Toscano for salad dressings, etc.
I guess you can see I love Costco. I live at least 50 miles from the closest to me, so also use Sam's Club because there's one close by.
I don't think the store here has as many interesting items as some in California do, but it's still a great place.
