10 Costco Essentials You Shouldn’t Buy Anywhere Else


Costco is renowned for its bulk items, competitive prices, and quality products. While it’s tempting to fill your cart with everything in sight, certain items stand out as true essentials that are best purchased at Costco. Here’s a guide to the top 10 Costco essentials that you shouldn’t buy anywhere else.

1. Kirkland Signature Olive Oil

Quality at an unbeatable price, Kirkland Signature Olive Oil is a pantry staple. Known for its purity and taste, it’s perfect for cooking and dressings.

2. Batteries

Buying batteries in bulk can save you a trip to the store later. Costco’s prices for batteries, especially their Kirkland brand, are competitive and offer great value.

3. Organic Eggs

Costco’s organic eggs are not just competitively priced but also come from high-quality sources. Buying in bulk ensures you won’t run out quickly.

4. Pharmacy Items

From prescription drugs to over-the-counter medicines, Costco’s pharmacy offers lower prices compared to other drugstores. Their generic brands are particularly cost-effective.

5. Kirkland Signature Nuts

For quality and value, Kirkland nuts are a must-buy. The variety and freshness, combined with their bulk pricing, make them a smart purchase.

6. Tires

With frequent promotions, quality service, and great pricing, buying tires at Costco can lead to significant savings, plus they offer lifetime maintenance services.

7. Gas

Costco’s gas prices are often much lower than other stations. If your routine involves passing by a Costco, filling up here can lead to substantial savings over time.

8. Rotisserie Chicken

A popular item for a reason – Costco’s rotisserie chicken is not only delicious but also priced lower than many competitors, making it a great deal for a quick meal.

9. Kirkland Signature Alcohol

From wine to spirits, the Kirkland Signature alcohol line offers exceptional value. The quality often rivals more expensive brands.

10. Optical Goods

Costco Optical offers great prices on eyeglasses and contact lenses, often beating out traditional optical stores in both price and service.

Why These Items Stand Out

Each of these items is not just about the savings; it’s also about the quality that Costco offers. Their Kirkland Signature brand, in particular, is synonymous with high standards and affordability.

Tips for Shopping at Costco

Plan Ahead: Know what you need before you go. It’s easy to be overwhelmed by the variety and size of the store.

Compare Prices: While Costco offers great deals, it’s still wise to compare prices with other retailers, especially for electronics or clothing.

Consider Storage Space: Buying in bulk is cost-effective, but make sure you have enough space at home to store your purchases.

Use the Costco App: For additional savings and convenience, use the Costco app to check for current deals and discounts.


Costco is more than just a warehouse club; it’s a hub for quality products at great prices. The key to making the most out of your Costco membership is knowing what to buy and what to skip. The items listed above are not just good deals; they are products where Costco consistently beats the competition in both quality and price.

Smart shopping at Costco can lead to significant savings and a satisfying shopping experience.
