20 Items You Should Buy At Costco

Are you the happy owner of a Costco membership carb or you are thinking of getting one? Learn what you should put on your shopping list before heading into the warehouse.


People who go to Costco love it so much. We usually shop there to buy certain products in large (huge!!) quantities. Not all products should be bought there. But, some are very, very good buys! Heading to Costco every now and then can be extremely beneficial to your wallet. Some items like prescription glasses, almond milk, brands of butter, fresh foods, are awesome deals. Bonus, they taste awesome! Costco only sales the very best products, this is a fact! This giant can choose who they order their stuff from, making quality the highest criteria.

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. Here are 20 products to buy from Costco!

1. Roasted chicken

Journal des femmes Cuisine

Ivo Parashkevov, the creator of Charlie, an artificial intelligence robot with personal finances, said paying $4.99 for Costco’s cooked roast chicken is a good deal. Add a pre-prepared salad, he says, and “it’s a perfect dinner for a family of four” for less than $10.

2. Kirkland bacon

The Fermented Pig

Costco’s Kirkland sliced bacon received a rating of 3.3 out of 5 from reviews of consumer reports, with negative aspects that have more to do with the amount you have to buy at once (bacon packages are in packs of four) than with the taste.

3. Fresh eggs

Parashkevov sees two advantages to buying eggs from Costco: excellent prices and variety.

“They have a surprising choice when it comes to eggs,” he says. You can buy everything from conventional eggs to outdoor eggs, all at a lower cost than in many other grocery stores.”

Prices vary by region, but Reddit users have reported prices below $5 for five dozen eggs and $3 for three dozen eggs in their local stores.

4. Kirkland organic almond milk


A good purchase you can make at Costco is Kirkland almond milk. The Dashing Dish blog praised this food as something that can go anywhere from smoothies to lattes.

Costco’s food court is so popular that it made headlines when the warehouse store changed the menu last summer. And the vegans were delighted. Instead of walking past pizza and hot dogs with an empty stomach and a heavy heart, people who don’t eat meat can now choose a bowl of herbal acai for $5.

6. Olive oil


If you like olive oil, the money you save on Kirkland organic olive oil could quickly pay the cost of your Costco membership. Samin Nosrat recommended this brand of olive oil in his bestseller, Salt, Fat, Acid, Heat: Mastering the Elements of Good Cooking.

7. Organic almond butter


Organic nut butter is a healthy source of protein, but they can be expensive.

Grace Guffin on the Cooking Light blog praised Costco’s private label organic almond butter in an article entitled The One Item That Makes a Trip to Costco So Worth It.

“This beautiful 27-ounce almond jar costs only $8,” said Mr. Guffin, making it much cheaper than what you can find elsewhere.

8. Cheese

Parashkevov says he has a weakness for fancy cheeses, and the Costco Cheese Alley is a corner of paradise for him. His favorite variety is Humboldt Fog.

“I think you can usually get a big piece for well under $20,” he says, adding that it would make it easy to feed guests “for three or four meals in two weeks.

Parashkevov also recommended buying Parmesan cheese from Costco. “Per unit, it’s very, very cheap,” he said, and its shelf life is longer than most cheeses.

9. Breakfast cereals

Organic berries are an exception to the warning for fresh produce.

Berries have great health benefits, but they can be expensive. Costco’s bargains on fresh berries can help you add this excellent antioxidant-rich food to your daily diet.

Costco’s berry quantities may also be a little easier for the average consumer to manage – an optional 18-ounce pack of blueberries, for example.

12. Vanilla extract


A 16-ounce bottle of pure vanilla extract can cost up to $30 at Costco, about 30% less per ounce than at other stores. And the Costco version is pure vanilla, not vanilla flavor, so you pay for quality. Today show recommended this product to anyone who likes to cook because it will last a long time.

13. Kirkland organic coconut water

For just over what you would spend on a 16-ounce yogurt at the grocery store, you can get a 64-ounce Verka organic yogurt pot from Costco. This cultured milk product has a surprisingly long shelf life, and its taste and texture are comparable to those of other whole milk.

15. Kerrygold butter


Costco sells several brands of butter, including Kirkland brand organic butter sticks. But if you want high-quality butter, gourmets prefer Kerrygold, made with milk from grass-fed cows.

16. Kirkland maple syrup


Maple syrup is a favorite at Costco. Not only is Kirkland maple syrup organic and pure, but it’s also a great deal.

If you regularly take an over-the-counter medication such as ibuprofen, Tagamet or an allergy pill, you will probably exhaust a quantity of Costco’s warehouse before it expires. You will pay a fraction of what these drugs would cost you in a pharmacy, and you will not lack an essential drug as often.

19. Prescription drugs


Prescription drugs can be expensive, even if you have insurance. Costco’s pharmacy offers such low prices, according to Consumer Reports, that you may be able to pay them without insurance. It is, therefore, worthwhile to file a prescription and have it filled while you are shopping.

20. Prescription glasses

Prescription glasses can be expensive, especially if you need progressive or other special lenses. One solution is to buy glasses online, but the fit and focus of the lens can be a problem with remote purchases.

Be aware that you can have your eyes tested at the store or bring your prescription for that matter – and if you don’t have insurance, Costco Optical may be a good solution.

Costco members also benefit from special online discounts for eyeglasses and contact lenses.
