10 Items You Shouldn’t Buy At Costco

Costco members usually go there because you get the best price on most products. That is a fact, but some items shouldn't be bought there. Not that it's not a great deal, but mostly because the large quantities might in fact be too much... or surprisingly pricier! Costco members, be careful with what you put in that huge cart!


Costco is known for offering great savings to its consumers. Most of the people in this store only go there to buy certain products in bulk, such as olive oil or golf balls. This is because the items are so big that it is not always smart to purchase them. They will only go to waste. It is not always advantageous to shop in this gigantic warehouse. While you buy certain products, food items and other necessities in a regular store, pharmacy or grocery store in order to prevent wasting money and food, heading to Costco every now and then can be extremely beneficial to your wallet.

While you should still buy some of your products in other stores, you must discover what is sold at Costco that should absolutely make it to your shopping list and into your larger-than-nature shopping cart and what to skip. Here are 10 products to avoid when shopping in this store.

1. Don’t buy fresh fruits and vegetables

Bio à la une

For many buyers, when you buy lots of fresh fruits and vegetables from Costco, it’s like buying the composter.

Costco has an abundant product section, with many fresh and healthy choices. But the quantities of perishable foodstuffs are too large for most households. You would probably be better off buying smaller quantities of fresh fruits and vegetables at the supermarket. This will reduce your loss.

2. Don’t buy milk (unless you have a large family)

“You can’t buy milk from Costco” because of the quantities offered, said Mr. Parashkevov.

There’s nothing wrong with the milk Costco sells, but you have to buy 2 gallons at a time. Unless you have many children to feed, it is probably impossible to drink so much milk before it becomes bad.

3. Don’t buy condiments

Serious Eats

Unless you are buying condiments for a family reunion, condiments are probably not a good purchase from Costco. Ketchup, mustard, and mayonnaise have a long shelf life, but not enough (unless you’re the kind of person who puts ketchup on everything – so go ahead).

Cheat Sheet noted that mayonnaise is only good three months after the expiry date and that even mustard turns against you after one year.

4. Don’t buy a Gas Signateur brand Grill

While Costco offers the Signateur gas grill for about half the price of a Weber grill, commentators on a Reddit grill said that its construction was not as durable as a Weber and that it might be difficult to find replacement parts.

A Reddit buyer summed up his regrets by buying this grill: “I have had this grill for just under a month and I am terribly disappointed by the lack of heat it applies to the food. With all burners at maximum, it doesn’t get hot enough to grab a steak or even put color on a hamburger patty without cooking the meat to the end.” Some comments about the Costco site grill echo the view that the grill simply does not provide enough heat.

5. Don’t buy some prepared foods


Costco offers many options for a healthier diet on a limited budget, but it may be better to use raw materials such as nuts, meats, and cheeses rather than some prefabricated food products such as chicken tikka masala or enchiladas.

6. Don’t buy flour, baking powder, or dry yeast


Flour has a limited shelf life, as do other bakery ingredients (e. g. baking powder and dry yeast). The Eat This Not That website warned against buying these items in bulk from Costco. If you do not operate a professional bakery, it is unlikely that you will be able to use these products before their expiry date.

7. Don’t buy Las Fortunitas tortilla chips


If your local Costco sells Las Fortunitas chips – those in a bag the size of a garbage bag – don’t buy them.

That’s not the price the problem; at less than $6, it’s an incredible offer. It’s not the taste, these chips are crisp and tasty. It’s just that you’ll probably never finish them.

8. Don’t buy paper towels and toilet paper


Large packages of Kirkland toilet paper or paper towels can be a good deal, but not if you live in a small apartment where you don’t have storage space for all these products…

9. Don’t buy light Kirkland beer


When Costco launched a light beer, the fans were enthusiastic. Then they drank it. It wasn’t good. A reviewer from Beer Advocate said it tasted like battery acid. With such criticism, it is tempting to taste it yourself just to see if you agree. But you’ll have to buy 48 cans, so just forget about it…

10. Don’t buy hearing aids


Hearing aids are a major expense that may not be covered by insurance. Costco sells them at a low price and takes a small surcharge.

Despite the good price, you may want to think twice before buying a hearing aid from Costco. Customers have reported poor service in some Costco stores. And some places may not have the right equipment to properly adjust your hearing aid.
