In general, I have found that Costco prices on most items beat those in grocery stores and even Walmart. In many cases, I don’t buy the Costco item, not because it’s too expensive, but because I don’t need the large quantity, either number of items or size. I’ve gotten large packages of food with an expiration date 18 months away and find myself still throwing things away. Costco TP and paper towels last forever, but bags of dried cranberries and the like definitely don’t last forever. Many sizes and quantities are a great value for large families, not so much for just 2 people. This is especially true for perishables. 6 large red peppers are a great deal, but the last 2, or even 3, end up wrinkled and decaying by the time we use them. OTOH, as long as you have the room, you can’t beat them for non-perishables. Given the price of gas these days, running around looking for sales items generally doesn’t make any sense. Everybody dislikes some store they avoid. For us, Costco isn’t one of them.
