10 Kirkland Signature Products Costco Shoppers Regret Buying

Costco’s Kirkland Signature brand has a loyal following, and many shoppers trust it for high-quality goods at reasonable prices. However, not every product under the label receives universal praise. Over the years, Reddit threads, consumer reviews, and expert roundups have highlighted certain items that fall short of expectations. Issues range from flavor and texture problems to inconsistency or poor value compared to national brands. These shoppers ‘ disappointments can help guide your next Costco trip, especially if you are stocking up in bulk. Here are ten Kirkland Signature products that buyers most frequently say they regret bringing home.

1. Kirkland Signature Bacon Crumbles

Kirkland Signature bacon crumbles appear on several regret lists because many shoppers feel they lack the flavor and texture of freshly cooked bacon. Reviewers on Reddit report that the pieces tend to be overly dry or tough, with some describing them as more leathery than crispy. Others note that the bits taste smoky in an artificial way, which becomes noticeable in salads and baked dishes. While the bulk size offers value, the quality gap compared to pan-cooked bacon or premium packaged crumbles makes this product frequently mentioned as a skip.

2. Kirkland Signature Lobster Bisque

Although the idea of a budget-friendly lobster bisque sounds appealing, the Kirkland Signature version receives heavy criticism for both flavor and texture. Shoppers say the soup tastes overly sweet or overly fishy, with a thin consistency that does not resemble traditional bisque. Some mention an unpleasant aftertaste they cannot identify, while others note a lack of authentic lobster pieces. These issues are echoed in Reddit discussions and food roundups that label the bisque as a letdown. For those wanting a rich seafood soup, many reviewers recommend opting for a name-brand alternative.

3. Kirkland Signature Espresso Blend Coffee

Costco offers several well-liked coffees, but the Kirkland Signature espresso blend stands out as a disappointment to many shoppers. Online reviews describe the beans as overly oily and producing a bitter or burnt-tasting brew, even when prepared with high-quality espresso machines. Some users also complain that the flavor becomes flat quickly after opening the bag. With espresso, small differences in roast quality can dramatically affect taste, making this blend a risky purchase in such a large format. Many buyers say they switched to smaller bags of premium coffee for a more reliable result.

4. Kirkland Signature Rotisserie Chicken

The Kirkland rotisserie chicken remains popular for its price, yet many shoppers argue that the quality has declined. Consumer posts mention increased saltiness, uneven cooking, and a slightly chemical flavor that some find off-putting. Although the chicken is still a bargain, its sodium content of around 460 milligrams per serving raises concerns for those monitoring salt intake. These complaints have led some longtime buyers to look for alternative options or roast their own at home. While still convenient, it appears to be one of the more divisive Kirkland products today.

5. Kirkland Signature Protein Bars

Protein bars are intended to be convenient and nutritious, but the Kirkland Signature version often receives negative reviews for texture and digestibility. Shoppers describe the bars as dense, chalky, or difficult to chew, with some reporting stomach discomfort due to the sugar alcohols used as sweeteners. Although the bars contain high protein content at a competitive price, many people find the experience unpleasant enough to avoid purchasing them again. On Reddit, several users say they prefer spending a little more for better-tasting alternatives that feel easier on the stomach.

6. Kirkland Signature Batteries

Kirkland Signature AA and AAA batteries receive mixed reviews, with many shoppers regretting the bulk purchase due to leaking concerns. Numerous Reddit users share images of the batteries corroding inside remotes or toys, sometimes ruining the device. While the price is appealing, buyers note that the shelf life feels shorter than expected and that the batteries cannot match the long-term performance of premium alkaline brands. Because batteries can damage electronics when they leak, many customers say they now spend a little more for trusted name-brand packs.

7. Kirkland Signature Organic Tomato Sauce

Tomato products should taste vibrant and fresh, but Costco shoppers report that the Kirkland Signature organic tomato sauce does not meet expectations. Many describe the sauce as overly acidic or metallic, making it difficult to use in simple pasta dishes without adding extra ingredients to balance the flavor. In Reddit discussions, some shoppers say they use it only when the sauce will be heavily seasoned or cooked into larger recipes. Because it is sold in large multi-packs, buyers feel stuck with cans they do not fully enjoy, which adds to the regret.

8. Kirkland Signature Milk Chocolate Raisins

Milk chocolate raisins are a crowd-pleasing treat, but the Kirkland Signature version is criticized for being far too sweet. According to consumer guides, the coating contains corn syrup and creates a sugary flavor that overwhelms the raisins rather than complementing them. Some find the texture inconsistent, with thicker chocolate shells that feel heavy and cloying. While the value-sized container is appealing, many buyers regret purchasing such a large quantity of a snack they find difficult to finish. Those seeking a more balanced candy often prefer branded options.

9. Kirkland Signature Original Spiced Rum

Costco’s private label spirits receive mixed reviews, and the original spiced rum is one that many shoppers regret. Reddit posts describe the flavor as harsh, overly sweet, and leaning heavily on artificial vanilla and smoky notes. When mixed into cocktails, the rum can overpower other ingredients instead of blending smoothly. Some buyers also report a lingering aftertaste that makes the rum difficult to drink even in small amounts. Despite the attractive price, the disappointing flavor profile leads many to return to well-known rum brands.

10. Kirkland Signature Frozen Pepperoni Pizza

Frozen pizza is a convenient dinner option, but the Kirkland Signature pepperoni pizza struggles to compete with its national brand counterparts. Online reviewers say the crust bakes into a dense or rubbery texture, while the cheese and sauce lack depth of flavor. The pepperoni is sometimes described as greasy without delivering much spice. Shoppers note that the pizza looks promising in the box but does not match expectations once baked. Because it is sold in a multipack, buyers regret committing to several pizzas that do not satisfy.
