I usually shop at Costco near me once per week, especially now that they still have the 9-10 'senior' hours. It typically isn't busy at that time. We buy bananas, wine, milk (sold by gallon here), eggs, Kirkland whole bean coffee (really Starbucks at half the price), specials, laundry supplies, water, salmon, paper products, and some meats. Meat and salmon prices have almost doubled in past few months like most other places. Lamb chops are still a good buy at $8.99. I used to buy more produce, but our Costco has converted to mostly organic and I know it isn't worth the premium I worked in agriculture.) The pumpkin pies are now a great bargain for $5.99. The Krogers in our area are terrible, so we buy about 1/2 our total groceries at Costco.
When we go on vacation, we always stock up on wine and other key supplies at Costco on our first day. We have been disappointed that many no longer carry the large spinach salads. These were great for salads the first few days, and scrambled eggs later in the week, We have been disappointed that they have stopped carrying many of our favorite items (including pizza) and are trying to force people to buy higher margin things. They are building a new Costco about 15 miles from us and are likely to close the one that is much closer. That will greatly reduce our shopping at Costco if they do.
