Based on my math and this particular haul, Costco generally offers lower prices.
However, the only way to reap the benefits is to purchase bulk-sized quantities, which isn’t for everyone. The real value depends on how much you can reasonably consume.
Produce is the perfect example. It’s hard to eat six heads of romaine or 10 pounds of potatoes before they go bad, even for veggie lovers.
Although these items are cheaper at Costco, large packages make it easier to waste food (and therefore money). The same goes for Costco’s mega-sized spices, chips, egg cartons, and beyond.
Plus, Costco has a $65 annual membership fee, so you’d have to spend enough to make it worth it — though breaking even is an achievable goal for most shoppers, especially families, since Costco carries more than groceries. Members also get discounts on things like travel, rental cars, tires, and gas.
