With tariffs pushing grocery prices up, shoppers are having to get creative to keep their budget under control while restocking the pantry. While adding a new annual fee to the mix might seem like too much, signing up for a Costco membership – especially while you can take advantage of this deal to save $40 on it – can help rein in soaring food prices.
A Costco membership opens doors, quite literally, to a vast selection of bulk-size groceries and household goods sold at discounted prices. Buying potato chips and batteries by the case is just the start.

The warehouse club also stocks everything from tires and furniture to electronics and jewelry. In fact, with so many items to choose from, smart shopping expert Trae Bodge says it’s critical to bring a list to avoid overspending, particularly on seasonal items the store loves to put right inside the front door.
List or no list, shoppers seem to like the savings and selection. Costco has 132 million members around the world, with a 90.5% renewal rate worldwide. With these numbers, it's no surprise the chain ranks first in customer satisfaction among department and discount stores, according to the American Customer Satisfaction Index, edging out rivals Sam’s Club, Target and BJ’s Wholesale Club.
Thinking of taking the plunge with a Costco membership? Here’s what you need to know to get the most out of it.
1. You don’t actually need to be a member to shop
If you’re not ready to commit, there are still ways you can shop at Costco without a membership. If you want to check out the selection and compare prices, ask a friend or family member with a membership if you can tag along, as members are allowed to bring children and up to two guests. See something you like? The Costco member will need to make the purchase for you — cashiers check membership cards at checkout — but afterward, you can simply pay your friend back or go to the service desk and get a membership for yourself.
Alternatively, if you want to shop on your own without a membership, give that same friend or family member the money to buy you a Costco Shop Card. These gift cards are treated like cash and can be bought for as little as $25 (and go up to $2,000 in value). Non-members can flash the Costco Shop Card at the door to enter, shop and pay at any Costco location.
If you prefer online shopping, anyone can place an order at Costco.com. Just note that some products aren't available to non-members. And for products non-members can buy, there might be additional surcharges placed on the order.

2. Membership fees are higher than other warehouse clubs
Last September, Costco raised its membership fees. A Gold Star membership increased from $60 to $65, and an executive membership increased from $120 to $130. That officially makes it the most expensive warehouse club membership, though it's only slightly higher than Sam's Club ($50 and up) and BJ's ($60 and up) annual fees.
While it's a little more expensive to join, the added perks, overall product quality, and other services that Costco membership grants you can more than make up for the price hike.

3. You can get a good deal on a casket
Caskets are often the single most expensive item purchased for a traditional funeral service, according to the Federal Trade Commission. The average cost of a casket bought through a funeral home is more than $2,000, but depending on the finish, the price can climb as high as $10,000. Costco offers a cheaper alternative.
Members who may be planning a funeral can purchase a casket through Costco.com. The warehouse club’s inventory is manufactured by Prime Caskets. Prices range from around $1,149.99 for The Lord's Prayer Casket to $1,349.99 for the Hampton mahogany casket.
Before completing your purchase, call the casket provider at the number included with the product listing to confirm availability, pricing and shipping/delivery details. Once done, your order will be processed.
Standard shipping is included in the cost of the casket. Expedited shipping is available for an additional fee. Both the shipping address and the billing address must be in one of the 36 states (plus the District of Columbia) that are approved for casket sales.

4. The store return policy is generous (except on caskets)
There isn’t a time limit on returns or exchanges on most products sold at Costco. However, big-ticket items such as televisions, appliances and smartphones must be returned within 90 days of purchase in order to receive a full refund.
That’s still a much more lenient policy compared to other mass retailers that sell similar electronics. This includes Best Buy (most items must be returned within 15 days of purchase) and Target (items must be returned within 30 days of purchase).
Among the few exceptions are alcohol and tobacco, which can’t be returned where prohibited by law. Diamonds over 1 carat must be authenticated before a refund is approved. Shop Cards are also non-refundable.
As for the aforementioned caskets? All sales are final unless damage occurred during shipping.

5. You can even return your membership
Paid for a Costco membership but never used it? If, after joining Costco, you decide you aren’t getting the value you expected or you simply don’t shop enough to justify paying the annual fee, you can cancel your membership anytime and get your money back.
All you have to do is visit your local Costco, go to the membership desk and request to close your account. You can also call the Member Services Center at 1-800-774-2678. As part of Costco’s "Risk-Free 100% Satisfaction Guarantee," your membership will be canceled and you’ll receive a full (not prorated) refund of the annual fee on the spot — no questions asked and no cancellation fee.

6. 1 in 5 products are Costco’s Kirkland Signature Brand
About 20% of the items found at Costco are from its Kirkland Signature private-label brand. The product line includes everything from home goods and apparel to food and liquor. You can even order a 72-pound wheel of Kirkland Signature cheese.
Costco strives to make its branded items as good as or better than national brands, sometimes manufacturing its products in the same factories used by national brands. According to smart shopping expert Bodge, you can often save a few bucks by opting for the Costco brand over a national brand. However, compare quality as well as price. In quality testing, Consumer Reports gave low marks to Kirkland Signature toilet paper and facial tissue.
We put the prices of a few Kirkland Signature items that we found at a Washington, D.C., area Costco, to the test against similar name-brand products. Here’s what we found:
- A 30-roll pack of Kirkland Signature 2-Ply Toilet Tissue (380 sheets) cost $24.99, while a 30-roll pack of Charmin Ultra Soft 2-Ply Toilet Tissue (213 sheets) was $27.99.
- A 12-roll pack of Kirkland Signature Premium Paper Towels (160 sheets per roll) was $23.99, while the same size package of Bounty Paper Towels (101 sheets per roll) was priced at $29.99.

7. Some Kirkland products are really good value
Many store-branded products appeal to shoppers because they are cheaper than national brands. But cheaper isn’t always better. To identify some of the best Kirkland Signature products to buy at Costco, we homed in on items that are not only less expensive than national brands but also on par in terms of taste and quality. Here are a few of our favorite Kirkland products:
Kirkland Signature bacon, for example, bested top national brands, including Oscar Mayer, in testing by Consumer Reports. Although some consumers claim that in recent months the quality has gone down.
In a study of olive oils conducted by the University of California, Davis, Kirkland olive oil was one of only a few imported oils that met international and U.S. standards. And Kirkland batteries, which are manufactured by Duracell.

8. Buying in bulk isn't always a good deal
Buying household essentials in bulk seems like a no-brainer for your household budget. Not only can you save money but you can also save time by avoiding frequent trips to the supermarket. But, unless you're shopping for a large family or group, paying to join a warehouse club solely to gain access to bulk-packaged products might backfire, says Jeanette Pavini, a savings expert for Coupons.com.
"If the items you purchase in bulk expire or spoil before you finish using them, that’s money poorly spent."
Several staples are some of the worst things to buy in bulk at Costco. The two main reasons: Either they have a short shelf life or you can typically find better prices on them elsewhere.
Examples of risky bulk purchases include liquid cleaners containing bleach (its effectiveness diminishes after six months), cereal (sale prices at traditional supermarkets are usually less per ounce) and skincare products (they lose effectiveness over time, plus the risk of contamination rises the longer a container has been open).

9. You can buy low-priced organic foods
Costco may not be top of mind for many shoppers when it comes to buying organic foods, but it should be. The warehouse club offers a variety of organic products, including fresh produce, cooking oils and beverages at a lower price when you factor in the unit price.
We spot-checked Costco’s prices on a few organic items. Here’s what we found: A 16-ounce container of Earthbound Farm organic spring salad mix cost $5.39 (unit price: 34 cents per ounce) at Costco, while an 11-ounce container of Harris Teeter’s store-brand organic spring salad mix totaled $4.99 (45 cents per ounce) at a nearby location.

10. You can buy a car at Costco, too
Costco members in the market for a new ride can take advantage of the warehouse club’s auto program, which includes an online car-buying service.
Here’s how it works: You search Costcoauto.com for a new or certified pre-owned vehicle. Once you know the manufacturer’s suggested retail price (MSRP) for your desired vehicle, you can then locate nearby dealers who sell it.
You’ll be prompted to input your membership information and then be connected with a participating dealer. The dealer will contact you directly to schedule an in-person meeting where they’ll provide the Costco member price — no haggling required.
Costco’s Auto Program also allows members to save 15% on automotive parts and services on any of their household vehicles at participating service centers.

11. You can fill up your new car with Costco gas
A Costco membership can help you score lower prices at the pump. Select Costco locations have on-site gas stations for members that carry store-branded regular unleaded (87 octane) and premium unleaded (91 or 93 octane) gas.
Costco’s gas stations are self-service, and there’s only one way in and out to speed up transactions. Members can pay using any debit or credit card that's accepted in the store. Non-members can fill up and pay with a Costco Shop Card. Cash and checks are not accepted.
Plus, Costco members are finally getting what they've asked for. Longer hours at the pump. Gas pumps at all Costco warehouse locations in the U.S. are now open from 6 a.m. to 10 p.m., Monday through Friday. On Saturday, the pumps are open from 6 a.m. to 8:30 p.m. and on Sunday, you can pump gas from 6 a.m. to 7:30 p.m. Previously, pumps closed at 8:30 p.m. on weekdays.

12. Costco doesn't take coupons
Combining coupons from big brands with supermarket sales is usually a particularly effective strategy to lower your grocery bill, but it’s a strategy that won’t work at Costco. The warehouse club doesn't accept manufacturer’s coupons or discount coupons from outside retailers.
There is some consolation for Costco members: The company issues its own coupons, which can be found in a monthly printed booklet sent in the mail or on Costco.com. Costco's coupons can be viewed and redeemed in-store or online via the warehouse club's smartphone app.

13. You can get Costco groceries delivered to your doorstep
With a Costco membership, you can order groceries online thanks to a partnership with Instacart. Just click on "Same Day" in the navigation bar at the top of the Costco website and you'll be taken to a site where you can browse all grocery items that are eligible for same-day delivery in your area.
The order minimum is $35, and your order will be fulfilled by Instacart. If you choose to receive your items with Costco's two-day delivery, your order will be shipped and delivered like any other package, and there's no separate delivery fee for orders of $75 or more.

14. Non-members can use Costco’s pharmacy
The warehouse club’s pharmacy has long been lauded for its lower prices on many popular prescription medications compared to traditional pharmacies. Even better, non-members can take advantage of the deep discounts, too.
For non-members visiting a warehouse club location, simply let the door checker know that you’re headed to the pharmacy and they’ll direct you where to go, notes Kyle James, founder of Rather-Be-Shopping.com.
For members and non-members alike, before you’re able to fill prescriptions online, you’ll need to register on Costco’s website and create a patient profile. Once completed, you can place your order, as well as track your prescription’s processing and delivery status.

15. Members get alerts about product recalls
Product recalls are no laughing matter. Undisclosed peanuts in a packaged food item can cause severe allergic reactions in some people, and defective car seats and cribs can put children at risk. If you want to stay up-to-date on the latest product recalls from your favorite retailers, chances are you’ll have to do a bit of legwork to find them.
You either must go to the retailer’s website and navigate your way to the product recall section or follow their social media accounts. Alternatively, you can sign up for email alerts from various federal agencies that track product recalls.
However, Costco shoppers can rest easier. The warehouse club emails members directly whenever a product or food item they’ve purchased has been pulled from store shelves due to health or safety concerns.
The email will explain in detail why the item is being removed. It will also contain customer support contact details so you can learn more about how to return the faulty product and how to get a replacement item. Costco also maintains an archive of all its product recalls.

16. Learn to decode Costco price tags to spot deals
On your next Costco shopping trip, be sure to examine the product price tags carefully as you’re walking the aisles. That’s because the warehouse club has a price tag coding system that could help you score even bigger savings.
For example, even though Costco doesn’t widely publicize that it marks down items, there’s an easy way to tell: Any item with a price that ends with “.97” is a limited-time deal or special markdown, while prices ending ".00" usually indicate clearance deals.
Another price tag tip: If you spot an asterisk on the price tag, that means it’s probably not going to be restocked, so you may want to stock up before it disappears. There’s also a good chance the product has been significantly discounted.

17. Costco members can even save on getting married
Paying for a wedding can get pricey — quick. The average cost for a wedding totaled $33,000 in 2025, according to a study by The Knot. If you’re footing the bill for your big day, Costco can be a great resource, suggests Rather-Be-Shopping.com’s James. Brides- and grooms-to-be can find deep discounts on everything from engagement and wedding rings to floral arrangements.
James also points out that if you’re looking for budget-friendly wedding inspiration, there are plenty of Costco wedding hacks available online. This includes a DIY-tiered wedding cake made using two of their sheet cakes, as well as do-it-yourself wedding favors for guests. A simple Google search should steer you in the right direction.

18. You can create a gift registry featuring Costco and non-Costco items
If you’re planning a wedding or baby shower, consider creating a gift registry at Costco instead of multiple department stores or specialty stores. The warehouse club, in partnership with MyGiftRegistry.com, allows members and non-members to create gift registries for free. You can access the registry both online and in-store, and you can add everything from bottle warmers to cookware to fitness equipment, all in one place.
It’s important to note that while non-members can create gift registries, select products are exclusive to Costco members. This means you can’t add them to your online registry without a member login.
Additionally, your guests also won’t be able to purchase Costco members-only products if they’re non-members. So, be sure to include some items from other retailers on your registry.

19. Costco offers free extended warranties, tech support on electronics
The warehouse club is known for its deals on hot-ticket items such as TVs, computers and major appliances. Even better, Costco Concierge Services extends the manufacturer’s warranty on these items for up to two years from the date of warehouse purchase or the date of delivery if the item was purchased online.
All televisions, tuner-free displays and projectors qualify for the extended warranty coverage. Select computers and major appliances also qualify, but touchscreen tablets, refrigerators (above 10 cubic feet), freezers, range ovens, cooktop ovens, over-the-range microwaves, dishwashers, washers and dryers are excluded.
Costco Concierge Services also offers members free technical support by phone for most electronics purchased at the warehouse club.

20. Costco Travel can build your dream vacation for less
Planning your next vacation? Costco offers vacation deals to members who are U.S. residents through its online travel services department. This includes brag-worthy bargains on vacation packages, hotels, theme parks and rental cars.
Plus, the warehouse club promises members upfront pricing when booking travel: The price quote displayed throughout the transaction process includes all applicable taxes, so there are no surprises when it’s time to pay.
Costco offers vacation packages as varied as Hawaii to Costa Rica, to Italy, at a discounted price and with additional benefits. For example, the company often includes a resort credit, plus daily breakfast for two, in its time-limited packages. Browse all of Costco's travel deals to find discounts on trips to a variety of destinations.
Another bonus: If you aren’t a seasoned traveler, don’t fret. Costco makes it even easier to book your dream vacation by offering members live chat access to travel specialists, says smart shopping expert Bodge. With this member perk, “you’ll have someone who can help guide you through the process,” she adds.
