10 Worst Kirkland Brand Products You Should Never Buy at Costco

Costco, the retail giant, is renowned for offering a wide range of products at competitive prices. Among its private label brands, Kirkland Signature stands out. While many Kirkland products are beloved by consumers, not every item lives up to the reputation of quality and value.

In this blog post, we’ll shed light on 10 Kirkland brand products that you might want to think twice about before adding to your cart.

  1. Kirkland Signature Laundry Detergent:

While Costco’s laundry detergent might seem like a good deal, some users have reported that it doesn’t perform as well as other leading brands. The cleaning power and fragrance may not be up to par, making it a suboptimal choice for those who prioritize top-tier cleanliness in their laundry.

  1. Kirkland Signature Facial Tissues:

Facial tissues are a household staple, but Kirkland’s version may leave you with a rough experience. Some consumers have complained about the tissues being less soft and prone to irritation compared to other brands.

  1. Kirkland Signature Trail Mix:

Costco’s trail mix may seem like a healthy snack option, but a closer look at the ingredients reveals a high sugar content and an abundance of candy-coated components. If you’re looking for a truly nutritious trail mix, you might want to explore other options.

  1. Kirkland Signature Bacon:

Bacon enthusiasts beware – Kirkland’s bacon may not sizzle up to your expectations. Some customers have reported issues with inconsistent quality and flavor. Opting for a dedicated bacon brand might be a better choice for your breakfast indulgence.

  1. Kirkland Signature Shampoo and Conditioner:

Hair care is a personal choice, and Kirkland’s shampoo and conditioner may not suit everyone’s needs. Complaints range from the lackluster scent to the formula not providing the desired moisture or volume. Those with specific hair care requirements may want to explore alternative brands.

  1. Kirkland Signature Almond Butter:

While almond butter is a staple in many households, Kirkland’s version may not be the cream of the crop. Some users have noted a gritty texture and a slightly bitter taste. If you’re an almond butter connoisseur, you might want to stick to well-established brands for a smoother experience.

  1. Kirkland Signature Light Beer:

For those looking to enjoy a light beer, Kirkland’s offering might not be the best choice. Consumer reviews suggest that the flavor is lacking compared to other mainstream light beer brands. If you’re particular about your brew, exploring other options might be a wise decision.

  1. Kirkland Signature Diapers:

Parents are always on the lookout for reliable diapers, but Kirkland’s version might not be the most dependable. Some users have reported issues with leaks and discomfort for their little ones, prompting them to switch to other diaper brands.

  1. Kirkland Signature Jelly Beans:

If you have a sweet tooth, Kirkland’s jelly beans might disappoint. Complaints often revolve around the inconsistent flavors and an artificial taste. Candy lovers may find better options among established confectionery brands.

  1. Kirkland Signature Dog Food:

Even our furry friends aren’t exempt from scrutiny. Kirkland’s dog food has received mixed reviews, with some pet owners expressing concerns about the quality of ingredients and potential digestive issues. Considering the importance of a balanced diet for pets, exploring dedicated pet food brands might be a safer bet.


While Kirkland Signature products generally offer great value, not every item lives up to consumer expectations. Before stocking up on Costco’s private label, it’s worth considering alternative brands, especially for products that are essential to your daily routine or preferences.

Keep in mind that individual experiences may vary, and what works for one person may not work for another. Always check reviews and do a bit of research to ensure you’re getting the best bang for your buck on your next Costco shopping spree.
