10 Worst Kirkland Brand Products You Should Never Buy at Costco

10 Worst Kirkland Brand Products You Should Never Buy at Costco

ostco, the membership-based retail giant, is known for offering a wide range of products, including their in-house brand, Kirkland Signature. While many Kirkland products are praised for their quality and affordability, not everything bearing the Kirkland name is a wise purchase.

In this blog, we’ll take a closer look at the 10 worst Kirkland brand products you should avoid when shopping at Costco.

1. Kirkland Signature Toilet Paper

While Kirkland Signature is generally known for its quality, their toilet paper falls short of expectations. Many customers report that it is not as soft and durable as other brands. You might save money buying in bulk, but you might find yourself using more of it to compensate for its lack of quality.

2. Kirkland Signature Diapers

If you have a baby, Kirkland’s diapers might seem like a cost-effective option. However, these diapers are notorious for leaking and not providing adequate protection. The inconvenience and mess caused by diaper leaks may not be worth the savings.

3. Kirkland Signature Tuna

Tuna is a staple in many households, but Kirkland Signature canned tuna has received mixed reviews for its taste and texture. Some consumers find it overly fishy and not as enjoyable as other brands. Opt for a more reputable tuna brand to satisfy your seafood cravings.

4. Kirkland Signature Dishwasher Detergent

Nobody likes to rewash their dishes after they’ve come out of the dishwasher. Unfortunately, Kirkland’s dishwasher detergent doesn’t always get the job done. Many consumers have reported that it leaves dishes dirty and glasses cloudy, making it a less-than-ideal choice for keeping your kitchenware clean.

5. Kirkland Signature Almonds

Kirkland’s almonds might seem like a healthy snack, but some customers have complained about their taste and texture. They can be stale and lack the freshness you’d expect from almonds. It’s worth paying a little more for higher-quality nuts.

6. Kirkland Signature Light Beer

If you’re a beer enthusiast, you might want to steer clear of Kirkland Signature Light Beer. While it’s a budget-friendly option, it doesn’t compare to other light beers in terms of flavor. Beer lovers may find the taste lacking and opt for more well-known brands instead.

7. Kirkland Signature Multivitamins

Taking a daily multivitamin is a popular health choice, but Kirkland’s multivitamins have been criticized for their quality and effectiveness. Some users have reported that they lack key nutrients and may not provide the health benefits they promise. When it comes to your health, investing in a trusted vitamin brand may be a better choice.

8. Kirkland Signature Paper Towels

Like their toilet paper, Kirkland Signature paper towels are not as absorbent or durable as other brands. You may find yourself using more sheets to clean up messes, negating any cost savings. Investing in higher-quality paper towels can save you time and frustration.

9. Kirkland Signature Laundry Detergent

Clean and fresh-smelling clothes are essential, but Kirkland’s laundry detergent may not always deliver. Some customers have complained about its cleaning power, stating that it doesn’t effectively remove tough stains. For cleaner and fresher laundry, consider other detergent options.

10. Kirkland Signature Mayonnaise

Mayonnaise is a versatile condiment, but Kirkland Signature’s version is not highly regarded by many consumers. The taste and texture may not be up to par with other well-known brands. When it comes to enhancing your dishes, you may want to opt for a more trusted mayonnaise option.


While Costco’s Kirkland Signature brand offers a wide range of products, not all of them are created equal. Some Kirkland items may not meet your expectations in terms of quality, taste, or effectiveness. It’s essential to do your research, read reviews, and, when necessary, invest in alternative brands that deliver the quality and value you desire. By avoiding these 10 worst Kirkland brand products, you can make more informed choices during your next Costco shopping trip.
