Curious if a Costco membership could save you big on groceries? This members-only warehouse is known for offering everything from food to diapers to even caskets at low prices thanks to bulk buying—but is it right for you as a food shopper?
While Costco prices are often lower than grocery stores, it’s not a deal if you waste food due to spoilage or lack of storage. With grocery prices up by 22% since 2020 and budgets stretched thin, shoppers need clear ways to save.
Many loyal Costco members rave about the store’s great customer service, high-quality products, and exciting new finds, but is it worth getting a membership just for food shopping? Let’s break it down.

Costco Membership Options
To shop at Costco, you need a membership. Two options are Gold Star for $65 a year and Executive for $130. Both provide access to the warehouse, but Executive members earn 2% back on their purchases. If you’re unsure about how often you’ll use Costco, start with the basic Gold Star membership, and you can upgrade at any time during the year at the customer service desk.
While the membership fee should be considered, it’s important to factor it into your overall grocery budget. Many people recoup the cost quickly through savings.
Cost vs. Savings: Is It Worth It?
With a $65 membership fee, how long will it take to break even?
Here are some sample prices for common grocery items at Costco versus a regular grocery store:
| Item | Costco Price | Grocery Store Price |
|---|---|---|
| Two Dozen White AA Cage-Free Eggs | $5.69 | $7.58 |
| Gallon of 2% Milk | $2.55 | $3.79 |
| Boneless Skinless Chicken Breasts (per pound) | $2.99 (6 lb average) | $3.99 (6 lb average) |
| Two Loaves Pepperidge Farm Hearty White Bread | $5.69 | $9.98 |
| Six Romaine Hearts | $4.69 | $9.98 |
| Three Pounds of Bananas | $1.49 | $2.38 |
| Eight Cans of Goya Black Beans | $7.77 | $9.44 |
| Total | $45.84 | $67.12 |
The savings on these basic groceries is $21.28. If you shop at Costco just a few times, you could easily offset the membership cost.
Variety and Quality
Costco offers a wide range of grocery products, from quality meats and cheeses to frozen and pantry items. Whether you’re looking for organic, keto-friendly, or other specialty items, Costco has options.
While you can do the bulk of your grocery shopping at Costco, you might still need to visit a regular grocery store for smaller quantities and highly perishable items.
One of the biggest perks is access to Kirkland Signature products, Costco’s store brand known for high quality and low prices. Popular items like Kirkland’s olive oil, toilet paper, and rotisserie chicken have built a loyal following.
Special Deals and Discounts
Costco is known for its low margins but offers frequent sales, typically 20-30% off regular prices. While some sales are advertised monthly, many aren’t. For the best deals, be sure to sign up for our weekly newsletter, where we highlight the latest food discounts.
Items like Rao’s Marinara Sauce and Keurig K-Cups often go on sale, allowing you to save even more. One favorite is Tate’s Cookies—Costco offers them for as low as 35 cents per ounce, compared to 90 cents at a regular store!
Hidden Costs and Considerations

While Costco’s prices are great, there are other things to consider, such as the membership fee and the challenge of buying in bulk. While products like milk are sold in familiar sizes, many items come in larger quantities, which can be difficult for smaller households or those with limited storage space.
Perishable items, like eggs and bread, may spoil if not used quickly. However, many items can be frozen to extend their shelf life, and tools like vacuum sealers can help, provided you have enough freezer space.
Who Should Food Shop at Costco?
Costco isn’t the best fit for everyone. The savings can make the membership worthwhile if you have the storage space and don’t mind buying in bulk. But it may not be as cost-effective if you don’t need large quantities or don’t have room to store items.

I miss some items Costco no longer carries. I mostly get my dry dog food and gas from Costco; however, Walmart Marketplace gas station (or at least is BY it) is cheaper than Costco.
Its only me and my dogs at my house so not sure if it’s still worth the membership cost
