11 Items That Are a Better Buy at Costco Than Sam's Club

If you're already paying for a warehouse club membership, you want to know you're getting the best value possible. Costco and Sam's Club look similar on the surface, but when you compare price per unit, quality, and package size, Costco often comes out ahead, especially for shoppers who plan ahead and buy staples. The trick is knowing which bulk buys deliver genuine savings and which ones only look like a deal because of the larger package.

For pre-retirees and retirees watching their monthly budget, these small price differences can add up to real savings over time. These are 11 items that are typically cheaper at Costco than at Sam's Club, based on per-unit pricing and comparable products. From pantry staples to household essentials and electronics, comparing the cost of each item can help you make your membership pay for itself.

With a few smart Costco membership perks and careful comparisons, these deals can make a noticeable difference.

Editor's note: Prices and availability are subject to change and may vary by location.

Cheese is one area where Costco shines. If cheese is a regular part of your meals, Costco offers better long-term value.

Shredded cheese prices vary by variety and location, but buying in bulk at Costco or Sam's Club can help you save on a staple you'll use in everything from tacos to casseroles. Compare the price per pound of similar cheeses before deciding which warehouse club offers the better deal. But in our experience, it's usually Costco.

The savings can be especially useful for households that cook often or go through shredded cheese quickly. Larger packages can help you avoid paying for several smaller bags at a traditional grocery store, and shredded cheese is easy to portion for different meals. You can use what you need right away and freeze the extra in smaller, airtight portions if the package instructions allow it. Just check the unit price on comparable varieties, since mozzarella, cheddar, and Mexican-style blends can have different prices.

Name-brand mayonnaise at Costco is often cheaper per ounce than brands sold at Sam's Club. A jar of Hellmann's Real Mayonnaise, for example, costs 14 cents per ounce, versus 15 cents per ounce at Sam's Club.

The larger gallon jar may feel like a commitment, but mayo has a long shelf life. For families or anyone who cooks at home often, Costco's price advantage makes this an easy win.

Mayonnaise is a useful staple for sandwiches, salads, dips, and homemade dressings, so buying a larger container can make sense if you use it regularly. Before stocking up, compare the price per ounce and the total amount you are buying. A small difference in unit price can add up when you go through several containers a year. Check the package's storage instructions, too, and refrigerate it as directed after opening. If you rarely use mayonnaise, a smaller jar may be a better choice, even if its unit price is higher, because it reduces the risk of wasting food.

Cleaning supplies are a big budget drain. At Costco, Cascade dishwasher pods are priced lower per pod than Sam's Club's same brand. Even a few cents saved per pod adds up over hundreds of cycles, making this a deal worth snapping up.

For a fair comparison, check that both packages contain the same Cascade formula and count. Different versions can have different prices, and a larger box isn't automatically the cheapest option. Divide the package price by the number of pods to see what each wash costs. If you run your dishwasher frequently, even a modest per-pod saving can add up over a year. Store pods in their original container in a cool, dry place, away from children and pets, and follow the label directions.

Frozen acai bowls at Costco are cheaper per bowl than similar Sam's Club acai bowls. They're convenient for quick breakfasts and healthier snacks, and Costco's bulk pricing and the additional two bowls in the pack lower the cost per meal, making it easier to enjoy premium frozen foods like acai without overspending.

The individual portions can also help make weekday breakfasts easier to plan. Instead of buying a more expensive smoothie bowl from a cafe, you can keep a frozen option on hand and prepare it at home. Depending on the product, you may be able to add fresh fruit, nuts, or granola to make it more filling, although those extras will add to the cost. Compare the total package price, number of bowls, and serving size before deciding which warehouse offers the better value. Check the nutrition label and preparation instructions, too. A lower cost per bowl is most useful when the product fits your tastes and eating habits.

Whether for snacks or baking, applesauce is a pantry staple, and Costco's store-brand Kirkland Signature multi-pack applesauce pouches cost less per pouch than Sam's Club's name-brand version.

The savings are especially noticeable for households buying applesauce regularly, and the long shelf life means nothing goes to waste.

Single-serve pouches are convenient for lunchboxes, road trips, and quick snacks at home, with no bowl or spoon needed. They can also be useful for grandparents who keep easy snacks on hand for visiting grandchildren. To make sure you're getting the best deal, divide the total price by the pouch count and compare similar package sizes and varieties. Organic and conventional applesauce may have different prices, so check the labels before comparing them. Keep unopened pouches stored according to the package directions, and avoid buying more than your household can reasonably use. A lower per-pouch price is a win only when the food gets eaten.

Frozen pizzas are a go-to for easy meals or entertaining grandkids, but not all options deliver the same bang for your buck.

Costco's Kirkland Signature pepperoni pizza comes in a 4-count pack for $14.39 ($3.59 each), while the comparable Sam's Club Member's Mark rising crust pepperoni pizza 3-pack runs around $13.76 ($4.59 each), making Costco more affordable per pizza.

That per-pizza difference can make a difference for families trying to keep dinner costs down. Costco's four-pack also gives you an extra meal compared with Sam's Club's three-pack, so you can stock the freezer for busy evenings or unexpected visitors. Frozen pizza can be an easy alternative to takeout when you don't have time to cook, although the actual savings depend on what you would otherwise spend on dinner. Prices and package sizes can change, so double-check both products before shopping. Also compare the weight and style of the pizzas, since they may not offer the same amount of food.

Electronics aren't always cheaper at warehouse clubs, but Costco frequently undercuts Sam's Club on popular items like AirPods, beating Sam's by charging $50 less for the Apple AirPods Pro 3. That kind of savings can make a difference when you're shopping for premium electronics, especially if you're buying multiple devices or trying to keep holiday and birthday spending in check.

Costco's pricing also sometimes includes extended warranties or better return policies, adding extra value beyond the sticker price, especially important for higher-cost purchases. Before buying, compare prices at both warehouse clubs and check whether either retailer offers additional perks that could help you save. Even a small price difference can add up when you're making several purchases, and checking both stores can help you avoid paying more than necessary for the same product.

Costco's steak prices can be lower per pound than Sam's Club's.

For shoppers who enjoy cooking at home, Costco offers a better balance of quality and price.

When comparing steak prices, look for the same cut, USDA grade, and trimming style. A boneless USDA Choice top sirloin steak, for example, isn't directly comparable with a USDA Prime steak or a different sirloin cut. Costco's meat department offers options for shoppers who want to prepare steak dinners at home, and buying a larger package can help if you plan to portion and freeze steaks for later meals. Check the price per pound on the package label instead of comparing the total package cost, since meat packages can weigh different amounts. Properly portioning and freezing what you won't use soon can help reduce food waste and make a bulk purchase more worthwhile.

Bananas may seem inexpensive anywhere, but Costco offers a lower price per pound than Sam's Club.

For households that go through bananas quickly, this small difference can add up over months. It's a simple example of how everyday staples can quietly stretch your budget.

Bananas are an easy addition to breakfast, smoothies, and snacks, making them a practical item to compare when you shop at a warehouse club. Check the bag weight and total price so you can compare the cost per pound rather than the sticker price alone. Since bananas ripen quickly, think about how many your household will eat before they become overripe. You can use ripe bananas in baking or peel and freeze them for smoothies, which may help you get the most from a larger purchase. If your household eats only a few each week, a smaller bunch from a grocery store may be more practical. The best deal is the one that saves money without leading to waste.

If home security is a priority, and for many retirees it is, Costco's Arlo Ultra 4K 3rd Gen 3-camera bundle delivers superior value.

At $349.99 for three cameras plus the hub, this package brings the per-camera cost down significantly compared to what Sam's Club sells, where a 2-pack of the same model typically costs around $339. That's roughly $116.66 per unit at Costco versus about $169.50 per unit at Sam's Club.

That works out to a difference of about $52.84 per camera, based on the prices above. For shoppers looking to cover multiple entry points, the larger bundle may offer better value than buying fewer cameras and adding more later. Before purchasing, confirm that both listings include the same Arlo Ultra 4K third-generation cameras and comparable accessories. Check whether the hub is included, what storage options are available, and whether any features require a paid subscription. Those details can affect the total cost of ownership. Prices and bundle contents can change, so verify the listings before buying.

Costco offers iPads at prices that beat Sam's Club's.

Costco's return policy and bundled perks also add peace of mind. For retirees or grandparents buying tech for family use, this combination of price and protection matters.

An iPad can be useful for video calls with family, reading digital books, managing appointments, browsing the internet, and streaming shows. But Apple sells several iPad models, so compare the exact version before deciding which warehouse has the better deal. Storage capacity, screen size, and connectivity options can all affect the price. Check whether any bundle includes accessories you would otherwise buy separately, such as a case or charging accessories, and compare the final checkout price. A discount is most valuable when you're getting the features you need without paying extra for unnecessary upgrades. Reviewing the return policy before buying can also help you feel more confident about a larger purchase.

Costco's biggest advantage isn't just lower prices, it's consistency. Knowing which items reliably cost less helps you plan smarter shopping trips and avoid impulse spending. Pairing these savings with smart strategies to save money on groceries can stretch your monthly budget even further.

Another way to maximize value is timing your purchases around Costco's regular rotation of sales. Combining bulk buying with careful planning is one of the easiest ways to keep everyday costs under control without feeling overwhelmed.

The key is to focus on items you know you'll use before they expire or take up too much storage space. Compare unit prices rather than looking at the total cost alone, and avoid buying something in bulk just because it seems like a bargain. With a little preparation, Costco can help you get more value from your grocery budget while keeping unnecessary spending in check.
