12 Costco Brand Products Shoppers Say to Skip

December 5, 2025

When shopping at Costco, many members turn to Kirkland Signature products for their great value and quality. However, not all Kirkland items hit the mark, and some have left shoppers feeling disappointed. While these products often offer a budget-friendly alternative, they may not always live up to expectations in terms of performance or taste. These are some of the most commonly criticized Kirkland items and why they might not be the best choices for your next Costco run.

Kirkland Signature Organic Marinara Sauce

Kirkland Signature Organic Marinara Sauce is often considered a go-to for pizza and pasta nights, but many shoppers say it misses the mark on flavor. While it boasts organic ingredients, it tends to have a more watery consistency compared to other marinara sauces. Some find it lacks the rich, savory taste that is expected from a premium sauce. The price is often attractive, but for those who prefer a thicker, bolder sauce, it may fall short. The flavor can come off as too acidic, with a slight lack of depth in its seasoning. For those looking for a classic, robust marinara sauce, it might be worth exploring other brands. This product could be perfect for those on a tight budget who are willing to compromise on taste.

Kirkland Signature Laundry Pods

Many Costco members have expressed disappointment with the Kirkland Signature Laundry Pods due to issues with their effectiveness. Some customers report that the pods do not dissolve well in certain washing machines, especially in cold water cycles. While they are generally less expensive than other high-end brands, the quality sometimes leaves a lot to be desired. Many users feel the scent is too faint, leaving clothes smelling less fresh than expected. The pods may not be as powerful at removing stains, particularly tougher ones. For those looking for a strong, consistent clean, there may be better options available. The value may seem appealing, but the performance does not always match the price.

Kirkland Signature Batteries

While Kirkland Signature Batteries are often praised for being affordable, shoppers are quick to point out that their performance can be inconsistent. Some report that the batteries do not last as long as other premium brands, especially in high-drain devices. They may work fine in low-power items like remote controls, but struggle in devices that require more power. The price is a major selling point, but when compared to longer-lasting alternatives, they may not offer the best value in the long run. They also tend to leak more than expected in devices that are left unused for extended periods. Shoppers seeking reliability might consider paying a bit more for a brand known for longevity. The convenience and price of Kirkland Signature Batteries could be appealing for occasional use.

Kirkland Signature Sliced Turkey Three-Pack

Kirkland Signature Sliced Turkey has garnered mixed reviews, with some shoppers finding it a bit too dry for their taste. Although it offers great value in terms of quantity, the texture does not always match up to the expectations of deli meats. The flavor is often described as bland, and it lacks the richness that some other deli turkey options have. For those who enjoy a juicier, more flavorful sandwich filling, this turkey might disappoint. It also has a slightly rubbery texture, which some customers find off-putting. If you are looking for premium-quality deli meats, this might not be the best option. However, it works fine for those on a budget who need to feed a family without breaking the bank.

Kirkland Signature Dishwasher Tabs

Kirkland Signature Dishwasher Tabs are a favorite for many, but some shoppers find that they do not clean as effectively as other top brands. Many report that dishes come out with residue or a cloudy appearance, especially on glassware. The tabs often fail to fully dissolve, leaving chunks in the bottom of the dishwasher. The scent is generally pleasant but does not linger as much as some would like. For those with particularly dirty or greasy dishes, these tabs may struggle to remove stains or grime. While the price is appealing for a large quantity, the performance often falls short of expectations.

Kirkland Signature Dental Chews

Kirkland Signature Dental Chews are designed to help clean your pet’s teeth, but not all pets seem to be fans. Many pet owners report that their dogs do not enjoy the taste, making it harder to get them to chew regularly. While they are cheaper than many other dental treats, their size and texture may not suit all breeds or chewing habits. Some users find that the chews do not do much for controlling bad breath or reducing tartar. They are also not as durable as other more expensive options, leading to faster wear. For pet owners who are looking for a trusted brand with proven dental benefits, this product might not be the best option. However, if your dog does enjoy them, they offer a budget-friendly solution.

Kirkland Signature Contact Lens Solution

Kirkland Signature Contact Lens Solution is another product that has left some users unimpressed. While it is priced lower than most name-brand solutions, some shoppers feel it does not clean or hydrate lenses as well. There are reports of irritation or dryness after use, which is not ideal for sensitive eyes. For those with more delicate eye health, the solution may not provide the comfort that premium brands offer. The lack of a multi-purpose formula can be inconvenient for individuals who prefer an all-in-one solution. Although it is effective for basic cleaning, it may not be sufficient for those who wear contacts for extended periods. It is a suitable choice for occasional use but not recommended for everyday wear.

Kirkland Signature Balsamic Vinegar

Kirkland Signature Balsamic Vinegar is often seen as a budget-friendly option, but it does not stand out in terms of flavor. Some customers note that it has a thinner consistency and lacks the richness found in higher-quality balsamic vinegars. It can be too sharp or acidic for some palates, leaving a less smooth taste in dishes. Those who enjoy the full, complex flavors of traditional aged balsamic might find this product lacking. The price point is appealing, but for those seeking authenticity in their balsamic, this product might not be the best choice. While it works fine for general use in recipes, it may not shine in a classic vinaigrette or on its own. If you’re looking for a more refined product, there are better options available.

Kirkland Signature Diet Green Tea

While Kirkland Signature Diet Green Tea offers convenience and a low-calorie alternative to sugary drinks, it often does not impress tea connoisseurs. Many report that it has a watered-down taste and lacks the fresh, earthy flavor found in higher-end green teas. The sweetness level can be overwhelming for some, and it may not have the subtle taste that green tea lovers prefer. Additionally, the artificial sweeteners used can leave an aftertaste that is less than desirable. The product works well for those who are looking for a quick, refreshing beverage on the go. However, for those who appreciate the true flavors of green tea, this product may not be satisfying.

Kirkland Signature Toilet Paper

Kirkland Signature Toilet Paper is often touted for its affordability, but some shoppers argue that it falls short in terms of quality. While it is soft, it can be too thin for some, leading to more sheets being used per visit. The paper tends to break apart more easily, making it less durable than higher-end brands. Although it is less expensive than many alternatives, the value may not be worth it for those seeking a more luxurious feel. It can also be rougher on the skin than expected, especially with sensitive skin types. Despite these drawbacks, it does the job for everyday use and is a budget-friendly option. If you do not mind sacrificing a bit of quality for a lower price, it could be a suitable choice.

Kirkland Signature Dish Soap

Kirkland Signature Dish Soap is a commonly purchased item, but many shoppers feel it does not clean as effectively as other brands. Some users report that it does not lather as much, making it harder to tackle greasy or stuck-on food. The scent can also be too strong for some, overpowering the dishes rather than leaving a fresh, clean aroma. For those with sensitive skin, the soap can cause dryness or irritation, particularly with frequent use. Although it is competitively priced, the performance is often considered subpar compared to other dish soaps on the market. For households looking for a more effective cleaning solution, this dish soap might not live up to expectations. However, it may work well for lighter cleaning tasks or those on a strict budget.

Kirkland Signature Rotisserie Chicken

Kirkland Signature Rotisserie Chicken is beloved for its convenience, but some customers feel the flavor can be inconsistent. While it is often juicy and tender, there are reports of dryness and overcooking in some batches. The seasoning can be too salty for some, overpowering the natural flavor of the chicken. Additionally, some shoppers report that the chicken is not as fresh as they would like, leading to a less enjoyable eating experience. The price is competitive, but for those seeking a perfectly seasoned, consistently juicy rotisserie chicken, this may not be the best option. It works well in a pinch, but it might not satisfy those who appreciate a higher quality meal.
