8 Costco Items With the Most Negative Member Reviews

January 27, 2026

When it comes to shopping at Costco, most people rave about the deals and quality they find in store. However, like any store, there are some products that just do not live up to the hype. If you are looking to avoid a purchase you might later regret, here is a rundown of some of the worst items at Costco, according to members who have been there and done that. These are the Costco items you might want to skip, known for being flavorless foods or not performing as expected.

Bananas

While Costco’s bulk pricing on bananas may seem like a great deal, it comes with the risk of unpredictable ripening. Some shoppers have reported buying green bananas that never ripen properly, leading to wasted produce. Others have had the opposite problem, with bananas going from unripe to overripe in what feels like an overnight transformation. The inconsistency can make planning meals around the fruit challenging. Many Costco members have shared their frustration with the bananas’ poor shelf life, which is often linked to improper handling or storage practices. Though some customers occasionally luck out with a decent batch, the overall reputation is negative. For dependable ripening and freshness, shoppers often suggest buying bananas from local grocery stores instead.

Kirkland Signature Spiced Rum

Kirkland Signature Spiced Rum has been widely criticized by Costco members for its unpleasant taste. Descriptions of the rum often compare it to artificial flavors, with some calling it “cinnamon hairspray,” which accurately reflects the overwhelming and off-putting aroma. Despite the affordable price, many customers feel that it fails to live up to the standard expected from Costco’s in-house liquor selection. One Reddit user even likened it to the taste of hand sanitizer, making it hard for others to recommend. Many shoppers suggest avoiding this particular rum, as the flavor quality simply does not meet the expectations of spirits drinkers. For those looking for a better experience, other Kirkland Signature liquors like vodka or gin are often favored. In short, this spiced rum has earned a reputation for being a poor choice among Costco’s alcoholic offerings.

Kirkland Signature Helles-Style Lager

Kirkland Signature Helles-Style Lager is another Costco product that has garnered plenty of negative feedback from beer enthusiasts. Despite its reasonable price, many find the lager to be disappointing, with a flat and underwhelming flavor. For those who appreciate a good beer, the lack of complexity and depth in taste leaves much to be desired. Some members have even likened it to cheap beer that is best suited for party situations rather than a true beer-drinking experience. Additionally, its lightness and lack of distinct character make it easy to forget as soon as the can is empty. Though not everyone shares the same opinion, many Costco shoppers prefer other lager brands that deliver more satisfying flavor. If you’re looking for a more enjoyable beer, it might be wise to pass on this Kirkland Signature offering.

Kirkland Signature Colombian Cold Brew Coffee

Kirkland Signature Colombian Cold Brew Coffee has earned a lot of negative reviews for its less-than-stellar flavor and texture. Many coffee lovers have pointed out that the cold brew lacks the rich, smooth qualities typically expected from this type of drink. Instead, the taste is often described as flat and unappealing, with some even noting a sulfur-like taste reminiscent of rotten eggs. This bitter experience has led several shoppers to return cases of the coffee, preferring other brands or even brewing their own cold brew at home. While it is marketed as a convenient, ready-to-drink option, the quality simply does not meet the standards set by other coffee brands. For coffee aficionados, it’s clear that Kirkland Signature’s cold brew falls short of delivering the satisfaction they’re looking for. It’s an easy product to avoid for those who take their coffee seriously.

Global Gourmet Hot Sauce Collection

The Global Gourmet Hot Sauce Collection might seem like a great gift idea for hot sauce lovers, but the reality is far from ideal. Shoppers who have purchased this 12-pack often complain about the lack of variety between the sauces, as many contain similar ingredients. Rather than offering distinct flavors, the sauces are described as being overly vinegary and lacking the depth of heat that fans of spicy food expect. For those seeking true heat and unique flavors, this collection falls flat, with many noting that it’s a subpar selection compared to individual hot sauce brands. Additionally, the artificial colorings in the sauces are a turnoff for some, further diminishing their appeal. It’s hard to recommend this pack when there are so many other quality hot sauce options available on the market. As a result, Costco shoppers often regret this purchase and advise others to skip it.

Kirkland Signature Burnt Ends Brisket

Kirkland Signature Burnt Ends Brisket is another Costco item that has disappointed many shoppers. While burnt ends are supposed to be tender, juicy, and flavorful, these brisket cuts have been described as tough and chewy, with a texture that many find unpleasant. Several Costco members have taken to online forums to complain about the lack of flavor and excessive fattiness, which makes it difficult to enjoy the product. One particularly negative review even compared the burnt ends to dog food, a harsh but clear critique. In addition to the poor texture, some shoppers have noted that the serving size is often misleading, offering less meat than expected. Despite the high price, the quality just does not measure up, leaving many with regret after their purchase. If you’re in the mood for quality brisket, it might be better to look elsewhere for a more satisfying experience.

Kirkland Signature Boneless Skinless Chicken Breasts

Kirkland Signature Boneless Skinless Chicken Breasts are frequently mentioned in Costco’s list of disappointing products. Shoppers who have purchased this product are often frustrated by its tough, rubbery texture, which makes it difficult to cook properly. Despite trying various cooking methods, many find the meat to be fibrous and overly chewy, detracting from the overall eating experience. For those expecting a tender, juicy chicken breast, this option has failed to meet those basic standards. Several customers have even recommended avoiding this product altogether, opting for fresh cuts from local grocers instead. The price may seem like a bargain, but the poor quality has led many to warn others about it. If you’re looking for quality poultry, there are better options available than these boneless, skinless breasts.

Kirkland Signature Bacon Crumbles

Kirkland Signature Bacon Crumbles are an enticing convenience product for those who love adding bacon to their dishes. However, the reality is that these bacon bits often fall short of expectations. Rather than being crispy and crunchy, they are often described as tough, dry, and rubbery, making them difficult to enjoy. Many customers have expressed frustration with the texture, which detracts from the crispy bacon experience they were hoping for. Some have even suggested microwaving the bits in an attempt to revive their crunch, but that seems to defeat the purpose of buying ready-to-use bacon crumbles. Additionally, the crumbles tend to spoil quickly, further reducing their value. For those who want authentic, crispy bacon, it is likely best to skip this product and opt for freshly cooked bacon instead.
