15 Costco Items I Confidently Skip Every Time I Go

There's a lot to love about Costco, but it's not a one-size-fits-all shopping experience.

It's not difficult to save money at Costco, which is why so many of us are avid fans of the big box juggernaut. Thanks to bulk items and competitive pricing, it seldom takes long for me to recoup the cost of my Gold Star membership.

However, not all Costco products mean I'll get the best price or that it makes sense for my household. From limited space in my freezer to finding better-priced deals at other stores, here are the Costco products I always skip — and why maybe you should, too.

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!

If you’re looking for a powerful rewards card that offers an extended intro APR period, look no further, the Wells Fargo Active Cash® Card checks that box too!

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). Which is great for someone who wants a break from high interest rates, while still earning rewards.

The best part? There's no annual fee.

Soft drinks

Costco sells a variety of soft drinks, from Coca-Cola products to sparkling water and more. The prices aren't bad, either.

But my local supermarket has BOGO sales on a regular basis, so I often can get a better price on these items.

Fresh produce

If you have a large family, buying fresh produce in bulk is a great way to ensure everyone eats their fruits and vegetables. But if you're not feeding a crowd (and I'm not), chances are something is going to spoil.

Plus, Costco's produce has, at times, been known to wilt faster than what I can get at the farmer's market.

Baked goods

Unless I'm going to a large potluck or hosting a party, I feel absolutely fine skipping the baked goods section at Costco. It's not to say they aren't delicious; plenty of people love these treats.

But fresh baked goods in bulk are perishable, and freezing them defeats the purpose of fresh.

Mayonnaise

Some condiments can last longer in your fridge than others, such as mustard and ketchup. However, mayonnaise, which is made from eggs, has a much shorter shelf life — about 4 months after opening as opposed to 1 year for the others.

Buying it in bulk (in this case, a 46-ounce container) means I'll no doubt end up wasting the majority of the product.

Books

Like many Costco shoppers, I'm an enthusiastic reader who loves books. And I enjoy perusing the book section to see what's new and popular.

But there's only one place I go to get books, and for a good reason: the library, which, as we know, is free.

Cat litter

The Scoop Away cat litter that Costco sells is a good deal; 42 pounds for $27.99 is especially cheap. However, the product is overhyped, something plenty of reviewers have pointed out.

Many lament the dusty, smelly formula that later turns muddy, adding that the quality used to be far superior.


Canned goods

This doesn't apply to all canned goods, as Costco has great deals on canned albacore tuna, for example.

However, you can get better deals if you're willing to do some price comparison at stores like Aldi and Walmart. For example, Walmart sells canned corn for $0.68 per can, whereas Costco's option costs $1.08 per can ($12.99 for a 12 count).

Frozen meals

Frozen meals are a convenient way to eat a relatively healthy lunch during the work week, and many have come a long way in terms of quality.

The issue is that Costco sells bulk packs of the same meal (like Amy's Lasagna), which leaves something to be desired in terms of variety.

Spices

Did you know that spices have a shelf life? That means you should be switching out your stock regularly to ensure they're fresh and potent.

So unless you're buying for a restaurant or have a very large family, you can skip buying bulk spices at Costco, as I do.

Get a protection plan on all your appliances

Did you know if your air conditioner stops working, your homeowner’s insurance won’t cover it? Same with plumbing, electrical issues, appliances, and more.

Whether or not you’re a new homeowner, a home warranty from Choice Home Warranty could pick up the slack where insurance falls short and protect you against surprise expenses. If a covered system in your home breaks, you can call their hotline 24/7 to get it repaired.

For a limited time, you can get your first month free with a Single Payment home warranty plan.

Quick tips: How to save on your grocery bill

Grocery shopping doesn't have to break the bank when you use the right strategies. Here are some of our favorite tips for reducing food expenses that we personally put to use:

  • Plan your meals around what's already in your pantry, then create a shopping list to prevent impulse purchases.
  • Buy store brands instead of name brands whenever possible.
  • Always make sure to compare unit prices, not just sticker prices.
  • Stock up on staples when on sale, but don’t ever buy just because something comes in bulk.
  • Shop the marked-down section for near-expiration bargains
  • 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 to handle every week, the savings can really add up. Double check in case your store also offers perks like gas rewards or any other discounts you might be able to take advantage of outside the grocery store.

Clothing

I'm not especially picky with regard to my fashion choices. But my issue with Costco clothing, even though it's popular for its style and affordability, is that it's often fast fashion made with synthetic materials — even Costco's pajamas.

If they offered other materials like cotton, wool, linen, etc, I might be more inclined to add clothing to my Costco shopping list.

Flour

Let's face it: 20 pounds of flour is a lot, even at Costco's great price of $19.99 for a two-pack of 10-pound bags from its Kirkland Signature brand.

I'm not an avid baker, so a smaller bag is all I need for use in my kitchen. Only a hardcore baker needs as much as Costco sells.

Gift cards

I seldom feel seduced by Costco's selection of gift cards, even if they do appear to be a great deal at face value.

There's a big chance the card will sit in a drawer until it expires. Plus, there's always fine print to get through and potential restrictions.

Pet food

The pet food at Costco is generally well-reviewed and popular with members. The prices are also extremely competitive.

However, I'm willing to pay more to feed my pets the formula recommended by my veterinarian, which Costco doesn't sell.

Frozen produce

Yes, really! I feel confident skipping the frozen produce section at Costco, and it's not because I'm not a smoothie aficionado.

It's that giant bags of frozen fruits and vegetables are susceptible to freezer burn unless you use them up within a few weeks. Plus, they take up a lot of space.

Cereal

If you have a large family who loves having cereal for breakfast, bulk can be the way to go. But it would go stale in my home before the box is finished.

Plus, local supermarkets often have BOGO sales on cereal, which can be a better deal than Costco's offerings.

Shopping pro tip: This month's best deals

April brings not just warmer weather and sunnier days, but also excellent shopping opportunities. With Easter happening on April 20, retailers will offer significant discounts on seasonal items at the end of the month, while also preparing for graduations, weddings, and spring cleaning season.

Here are some of the best deals to watch out for:

  • Cookware sets on sale for graduation and wedding season
  • Winter clearance items like coats and sweaters at end-of-season prices
  • Spring cleaning supplies with potential BOGO offers at stores like Target
  • Air conditioners before peak summer demand drives prices higher
  • Lawn care equipment as homeowners prepare for the growing season
  • Post-Easter candy and ham at deeply discounted prices once the holiday has passed
  • For groceries, consider seasonal produce like asparagus, broccoli, and spinach, which will be at their freshest and most affordable.

Remember that retailers are always thinking a season ahead. They're already preparing to get rid of spring merchandise while you're just getting ready to enjoy it. This makes April a great time to find budget-boosting deals of all kinds.

Bottom line

Shopping strategically at Costco is a smart way to save money, and few would be willing to argue that assertion. But not every product the bulk king sells is a fit for your kitchen, bathroom, or living room.

That's why it's best to include a variety of stores in your shopping agenda. No one store can do it all, but with some legwork, you'll get the best deals that suit your needs.
