As any devoted Costco shopper will tell you, Costco's incredible bulk deals can ensure that your membership more than pays for itself within a shopping trip or two.
But while Costco can help you save in general, not every Costco product is a bargain.
In fact, if you want to go easy on your budget, there are some products you should go out of your way to purchase anywhere but Costco — starting with the 10 items listed below.
Earn 2% cash rewards at grocery stores and Costco
The Wells Fargo Active Cash® Card(Rates and fees) is a powerful rewards card that allows you to earn unlimited 2% cash rewards on purchases — including on groceries, even at warehouse stores like Costco. New cardholders can also earn a one-time cash rewards bonus — $200 cash rewards bonus after spending $500 in purchases in the first 3 months!
This card also offers an intro APR of 0% for 12 months from account opening on purchases and qualifying balance transfers (then 19.24%, 24.24%, or 29.24% Variable).
The best part? There's no annual fee.

Electronics

Costco can be a great place to save on essentials like electronics, even laptops, phones, and accessories, but not always. Check to see that you are buying the latest model available; sometimes, selection is limited. And check that you are getting a lower price than you might get at an electronics retailer such as Best Buy.
Soda
/images/2025/05/04/costco-coca-cola-mini-variety-pack.jpg)
Unlike a lot of other Costco staples, sodas are sold in bulk in most grocery stores. As a result, most stores have soda deals, not just Costco. Unless you need a 36-count box of soda on short notice for a party, it's worth comparing soda costs between Costco and other grocery stores like Winco or Kroger to make sure you're getting the best price.
Fruits and vegetables

Since Costco's focus is on bulk items, it's never been particularly well-known for its produce. Produce like onions and potatoes typically last longer than berries and bananas, but most fresh produce will still go bad faster than a shelf-stable item like, say, chips or pasta.
Plus, buying fruits and vegetables in bulk can keep you from spotting obvious problems that might stand out in a smaller package. As a result, you might accidentally buy a half-moldy carton of strawberries from Costco without even realizing it — which means you'll have even less time to consume that entire bulk purchase before it goes bad.
Diapers
/images/2025/05/04/costco-kirkland-diapers.jpg)
Diapers won't spoil the way food will, but your baby can outgrow them, leaving you with diapers you can't use. Diapers are also difficult to store in bulk. So unless you are buying for triplets, it may be better to buy less elsewhere.
Shopping pro tip: This month's best deals

September marks the start of a new season and a new shopping mindset. As summer winds down, it's the perfect time to take advantage of transitional savings and post-summer sales. Look for deals on:
- Light layers and early fall fashion
- Outdoor clearance items
- Back-to-school essentials
- For grocery savings, grab peak-season produce, like apples, squash, grapes, and sweet potatoes
As retailers begin to roll out fall promotions, September is the sweet spot for scoring deals on both end-of-summer clearances and early autumn items. Shop now to get the best of both seasons.
Flour
/images/2025/05/04/costco-flour.jpg)
Flour doesn't spoil as fast as fruits and vegetables, but it still goes bad after a few months.
If you're an intrepid baker and you know for sure you'll be able to use an entire Costco-sized bag of flour within eight or so months, Costco's flour might still be a great bargain for you.
Otherwise, skip the bulk flour in favor of smaller packages at a regular grocery store, and don't forget to avoid raw cookie dough: no matter where you purchase it, flour can be contaminated with E. coli.
Chicken
/images/2025/05/04/costco-kirkland-chicken.jpg)
We're not talking about Costco's famous $5 rotisserie chicken, which the company plans to keep at its lower-than-low price for years to come.
Instead, we mean hand-trimmed chicken breasts, thighs, and legs—the typical meat you'd get at a poultry section at any grocery store.
While Costco's raw meat can save you money, it isn't necessarily a bargain, especially if you forget to freeze the meat you haven't cooked yet within a few days.
Kirkland Brand paper goods
/images/2025/01/31/costco-kirkland-bath-tissue.jpg)
Costco shoppers give rave reviews to most of its store-branded products, but not its Kirkland brand paper products. The toilet paper and paper towels are just not as durable and strong, so while the price is right, you end up using more of them. It can be a bargain to purchase in bulk, but not if you have to use the product up in volume.
Shoes
/images/2025/05/04/costco-new-balance-sneakers.jpg)
Costco frequently sells name-brand clothes at more affordable prices than many clothing outlets.
However, some Costco shoppers have bought cheaper brand-name items like shoes at Costco only to be disappointed in the quality and fit, speculating that Costco can sell branded items for less because it gets lower-quality inventory.
Low-quality running shoes can increase your risk of injury, so make sure your Costco shoes are good for your feet and knees as well as your budget.

Cooking oil
/images/2025/05/04/costco-canola-oil.jpg)
Like flour, cooking oil goes bad after a few months, so if you aren't sure you'll be able to use up a massive bottle of cooking oil in six months or so, your liter of Costco cooking oil isn't the bargain you think it is.
Quick tips: How to save on your grocery bill
/images/2024/05/10/mother-with-son-outside-grocery-store.jpeg)
Grocery shopping doesn't have to break the bank when you use the right strategies. Here are three quick tips for reducing food expenses:
- Buy store brands instead of name brands whenever possible.
- Always make sure to compare unit prices, not just sticker prices.
- Join your store's loyalty program so you don’t miss out on member discounts.
Even though something like choosing coupons in your grocery store app can feel like an annoying task, the savings can really add up.
Major appliances
/images/2025/05/04/costco-stove-convection-oven.jpg)
You might be able to find a cheaper-than-average water heater, barbecue, or other major appliance for sale at Costco, but make sure the item you buy is the right quality, brand, and price for the job.
For one thing, Costco's amazing return policy doesn't usually apply to appliances: you only have 90 days to return an appliance.
For another, Costco doesn't necessarily sell appliances at the lowest prices, so don't forget to check with other big-box stores like Target, Walmart, and Sam's Club so you can get the best deal on your costly product.
Bottom line
/images/2023/01/09/inside-shot-of-alaska-costco-store.jpeg)
Ask any budget-conscious Costco shopper: Costco can give you and your budget a fantastic shopping experience. But Costco's bulk food deals will backfire if you don't eat the food you buy before it goes bad.
And, you can't count on boosting your bank account with every single product you find on your local warehouse's shelves. As a money-conscious shopper, make sure you compare Costco's prices on individual products to the prices of the same items at smaller chains.
