Costco has a dedicated customer base thanks to its ample selection, competitive prices, shopping hacks, and overall pleasant customer experience.

It also has extremely high standards for its suppliers, which is likely why the following items are so popular with members and continue to be carried by the bulk big box king.

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.

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.

Kirkland Signature Rotisserie Chicken

Price: $5.66

In recent years, it feels like literally everything has gotten more expensive, but not the famous Costco rotisserie chicken.

It can feel like the last affordable option out there for a quick, healthy, and arguably tasty dinner: throw down some sides, and supper is ready.

The quality of the birds is also good. Otherwise, the retailer wouldn't sell 64 million of them every year.


Kerrygold Pure Irish Butter

Price: $16.33

One thing that has definitely gotten more expensive, thanks to inflation and supply chain issues, is butter.

Fortunately, Costco sells four 8-ounce sticks (two pounds) of Kerrygold Pure Irish Butter (salted) for less than $20. That's a cheaper unit price than you'll find at a regular grocery store.

The quality of the butter is also noteworthy, as some reviewers have praised it for its smooth consistency, pleasing color, and versatility in cooking and baking.

Pro tip: There's also an unsalted option for just a bit cheaper.

Kirkland Signature Frozen Organic Blueberries

Price: $9.64

If you make a lot of smoothies or eat your yogurt with fruit, chances are you throw the 3-lb bag of Kirkland frozen blueberries into your cart every time. For under $10, that's a good deal, and since they're frozen, they'll last a long time.

Registered dietitians praise this product because of its nutritional profile that is high in minerals, vitamins, antioxidants, and fiber, as well as the pleasant flavor. They even eat them on their own as a snack, which is quite the endorsement.

Kirkland Signature Creamy Almond Butter

Price: 10.09

Nut butters are known for their healthy advantages: They are high in fiber and protein, contain good fats that help your cholesterol levels, and increase your satiety. 

However, some brands can contain added ingredients like sugar or oils. Enter Kirkland's creamy almond butter that comes in a 12-ounce jar. 

This affordable option is made of just one ingredient: roasted almonds. No wonder it's won the praise of frequent Costco shoppers.

Oikos Triple Zero Yogurt

Price: $14.63

Continuing on the healthy food train, Costco sells an 18-pack of Oikos Greek nonfat yogurt for less than $15, meaning you're paying under a dollar for each individual cup. 

As for nutrition, this is a winner with 15 grams of protein and 3 grams of fiber per serving. Reviewers consistently cite the pleasing consistency and reasonably good flavor, factoring the macronutrient profile into the equation.

Frigo Cheese Heads String Cheese

Price: $14.59

Cheese sticks are nearly universally loved by children and adults alike. Kids like that you can play with your food, and grown-ups appreciate a healthy snack that both tastes good and has a decent amount of nutritional benefits.

Like butter, cheese has gotten more expensive. Fortunately, you can pick up a 60-pack of Frigo cheese sticks for under $15 at Costco. Customers point out the serious value of the product, with one calling them delicious as well.

Kirkland Signature Italian Style Beef Meatballs

Price: $22.59

Beef lovers, we haven't forgotten you. We just wanted to spare your wallet. That's why we suggest picking up the 6-pound bag of Kirkland frozen Italian meatballs next time you visit the big box juggernaut.

The package helps you save money shopping, and these meatballs are not only easy to prepare but also amp up pasta night and are great for a sub.

July is in full swing, bringing the height of summer. That also means peak season for hot deals and unbeatable savings. Now’s the time to save big on:

  • Grills, coolers, and outdoor living upgrades
  • Travel must-haves for road trips and beach days
  • Swimwear and summer fashion
  • For grocery savings, grab seasonal produce like watermelon, peaches, and tomatoes

While you're enjoying the sunshine, retailers are quietly making room for back-to-school inventory. That makes July a prime opportunity to scoop up summer favorites while the deals are still blazing.

Kirkland Signature Bacon

Price: $21.59

A second option at Costco for meat aficionados is Kirkland Signature Bacon, which you'll find in the refrigerator section. For a little over $20, you get four 1-pound packages, which is much cheaper than anything at the grocery store these days.

Reviewers say this bacon's quality blows the competition out of the water, as it crisps up nicely and tastes great alone, with eggs, or as part of a tasty club sandwich.

Great flavor, great texture, and great price, what more do you need?

Price: $20.99

Before the purists get mad about this selection, let it be known that none other than Chef Samin Nosrat put her stamp of approval on it.

This 2-liter bottle is Bureau Veritas-certified olive oil, meaning the oil has been sampled and tested under strict, third-party scientific guidelines. That's a bargain for the quality you're getting. No doubt it's a Costco staple.

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 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.

Bottom line

Cris C./Adobe las rozas madrid costco store

Costco is undoubtedly a popular shopping destination that can help you save money on groceries. Additionally, there are a host of other Costco products that people never regret buying.

Still, don't be afraid to try new things when you see them at the iconic bulk store, especially if you can sample them right then and there. Who knows what new products might become staples?
