10 Costco Items You Should Never Buy Only One Of

Kirkland Signature Extra Virgin Olive Oil

Costco’s Kirkland Signature Extra Virgin Olive Oil is a staple in many kitchens. Made from the first pressing of olives, this high-quality oil is used for cooking, dipping bread, dressing salads, and more. Many people buy this item because of its high-quality and affordability, but often overlook the fact that it comes in a large 2-liter bottle, making it a long-lasting purchase ideal for regular users.

Now, more than ever, people are cooking at home and using healthier ingredients in their recipes. Olive oil is rich in heart-healthy monounsaturated fats and antioxidants. The value of this product is undeniable, as one 2-liter bottle can last for months. Plus, according to a study done by the University of California Davis, Kirkland Signature Extra Virgin Olive Oil is one of the few imported oils that meets the quality standards for extra-virgin olive oils.

Kirkland Signature Toilet Paper

Kirkland Signature Toilet Paper is another Costco item that people should never buy only one of. Known for its softness, strength, and quality, this two-ply bathroom tissue is a staple in many households. Despite the bulk size, customers often neglect to purchase more than one pack at a time, despite the fact that toilet paper doesn’t expire and is always in use.

The need for this item has never been more evident than during the recent pandemic, when toilet paper shortages were common. Not only does buying in bulk save you the hassle of frequent trips to the store, but the Consumer Reports recommends Kirkland Signature Toilet Paper for its excellent balance of softness, strength and price.

Kirkland Signature Stretch-Tite Plastic Food Wrap

The Kirkland Signature Stretch-Tite Plastic Food Wrap is a product that many Costco shoppers swear by. Its superior cling, easy-to-use slide cutter, and large roll size make it a must-have for keeping food fresh. However, many people overlook the advantage of buying more than one roll at a time, despite its long shelf life and constant utility in the kitchen.

With the current trend of meal prepping and home cooking, having a reliable plastic wrap is essential. Not only does it help in preserving the freshness of the food, but it also reduces food waste. According to the Environmental Protection Agency, using products like plastic wrap can help in reducing food waste at home, which is now more important than ever.

Kirkland Signature Organic Peanut Butter

Kirkland Signature’s Organic Peanut Butter is a product that many Costco customers love. Made with just organic peanuts and sea salt, this peanut butter is a healthier alternative to many other brands that contain added sugars and palm oil. However, people often buy only one jar at a time, even though it’s a non-perishable item that can be used in various ways.

Nowadays, people are more health-conscious and are looking for cleaner, simpler food items. This peanut butter fits the bill perfectly. According to the Harvard T.H. Chan School of Public Health, peanut butter is a good source of protein and healthy fats. So, stocking up on this product isn’t just a bargain, it’s a smart health choice too.

Kirkland Signature Batteries are a household essential that people often overlook when shopping at Costco.
