Are These the Worst Buys at Costco? 9 Products Customers Keep Complaining About

We all love a good Costco haul—the giant carts, the bulk savings, the free samples. But let’s face it: not everything inside the warehouse lives up to the hype. While Costco is known for cult-favorite items and unbeatable deals, there are a few products that have sparked more eye rolls than applause from loyal shoppers.

From underwhelming prepared meals to awkward packaging fails and snack bars that taste like regret, some items leave customers wondering, “Did I just waste money in bulk?” These aren’t just nitpicks either—many of these products have generated consistent gripes on Reddit threads, Facebook groups, and customer reviews, with shoppers sounding off about bland flavors, strange textures, or just plain disappointing experiences.

So before you toss that meal kit or snack pack into your oversized cart, you might want to scroll through this list. Here are Costco food products that have received the most complaints—and what customers really think once they get them home.

1. Costco’s Butter Chicken with Naan Bread Meal Kit

Somewhere between authentic and convenient, Costco’s Butter Chicken with Naan Bread Meal Kit misses the mark for many. Customers often describe it as “very meh,” with an overly salty twist that drowns out the expected rich flavors of butter chicken. The naan, often soft and chewy, can’t save the meal from mediocrity.

Beyond seasoning, the meat quality becomes a sticking point, with chunks that lack tenderness and appeal. Priced higher than some anticipate, expectations for a hearty, delicious meal fall short.

2. Costco Food Court Roast Beef Sandwich

In the bustling rows of Costco’s food court, the Roast Beef Sandwich stands out—not always in a good way. Priced above its peers, this sandwich raises eyebrows and expectations. Unfortunately, many find it fails to deliver value.

The bread, often overly thick, overwhelms the filling of roast beef that lacks robust flavor. Cheese barely melts away the disappointment.

Pricey yet unimpressive, it’s a choice some might best leave behind.

3. Kirkland Signature Brisket Burnt Ends

The allure of smoky, tender brisket should be undeniable, yet Kirkland Signature Brisket Burnt Ends leave many wanting. Customers report a chewy, fatty texture that struggles to capture the essence of good barbecue. The lack of a genuine smoky flavor only adds to the regret.

Instead of the melt-in-your-mouth experience, these burnt ends often feel like a tug of war.

4. Kirkland Signature Protein Bars

Protein seekers, beware! Kirkland Signature Protein Bars have been a letdown for some.

Chalky textures and strong artificial sweetener aftertastes create a rather unappetizing snack. Whether post-gym or for a quick bite, the eating experience is less than ideal.

Some customers report digestive discomfort, a regrettable twist for health-conscious buyers. The bars, meant to fuel and nourish, instead puzzle with their formulation.

5. Costco’s Fresh Produce

Costco’s fresh produce, seemingly vibrant and inviting, has some buyers in a pickle. Reports of bananas browning prematurely and cucumbers turning soft too soon are common complaints. The allure of bulk buying sours when freshness fails to impress.

Mold and overripeness can be unwelcome surprises for customers expecting longevity. Regrettably, the promise of farm-fresh quality often wilts under reality, prompting shoppers to rethink their fruit and veggie choices.

6. Realgood Chicken & Pepper Jack Cheese Burritos

In the realm of quick and easy meals, Realgood Chicken & Pepper Jack Cheese Burritos fall flat for some shoppers. The burritos, described as bland and unappealing, bring disappointment rather than delight.

Taste and texture play pivotal roles in this negative critique. The chicken, likened to canned variety, lacks the savory appeal many seek.

Wrapped in a coat of mediocrity, these burritos fail to excite the palate.

7. Snapdragon Chicken Pad Thai

Snapdragon Chicken Pad Thai, with its promise of exotic flair, falls short of expectations.

Customers find the taste so off-putting that a quick disposal becomes the only solution. The noodles, lacking the desired blend of sweet and savory, disappoint. Chicken pieces add little to the culinary experience, leaving diners wanting more.

The frozen meal, though convenient, misses the mark on delivering authentic Thai flavors. For those hoping to indulge in a flavorful journey, this meal might not be the ticket. Instead, a lackluster affair awaits the unwary.

8. Kirkland Signature Mac and Cheese

Marketed as a comforting, ready-to-heat meal, Kirkland Signature Mac and Cheese promises creamy indulgence in a convenient package—but many shoppers say it falls flat on flavor. While it’s generously portioned and easy to prep, the taste has been described as bland, one-note, and lacking the rich, sharp cheesiness expected from a satisfying mac and cheese.

Customers have also pointed out the presence of tiny, nearly unnoticeable beef crumbles that do little to enhance the dish. Instead of delivering that cozy, nostalgic comfort food experience, this version feels like it’s missing a final flourish—a little more seasoning, a little more depth, and a lot more cheese.

9. Kirkland Signature Milk

A staple in households, Kirkland Signature Milk suffers from a design flaw more than a product issue. The square-shaped containers, intended to optimize space, leave some consumers frustrated. Pouring becomes a precarious activity, with spills more frequent than desirable.

While the milk itself maintains standard quality, the packaging design detracts from its usability. For families juggling tasks, ease of use becomes paramount, and here, the container design fails to deliver.

Functional but flawed, it’s a packaging puzzle worth pondering.
