6 Costco Products That Have the Most Customer Complaints

For all the ways people love saving money at Costco, there are still some products that just don’t make its customers happy.

In fact, these products garner entire Reddit threads of discontent. Not all of these complaints have to do with the product itself, but packaging, prices or even mold. Here are six products that have the most customer complaints.

Milk is milk, no matter how you package it, but Costco’s Kirkland Signature brand milk gallons get a unique complaint, according to Julie Ramhold, consumer analyst with DealNews.com.

“There isn’t anything wrong with the milk itself, but rather shoppers that are forced to buy the square-shaped containers absolutely despise them.” 

Ramhold said the shape is reportedly to make the milk easier to ship as well as cheaper and environmentally friendly, but shoppers who have had to use them talk about how it makes them prone to spilling milk whenever you pour.

“Personally, I can vouch for this one. I can’t think of a single time I’ve used those jugs and not spilled at least a little milk when pouring.” 

Costco appears to have heard the complaints on this one and plans to try to correct this problem, according to Eat This, Not That.

Costco fans have spoken and they’re unanimous. It’s much better to buy an in-club made chicken bake and skip the frozen ready-made option.

Several fans took to Reddit to complain that the frozen chicken bakes were among one of the worst Kirkland Signature items sold at the warehouse club. Apparently, the frozen version just isn’t the same as the real thing.

Chomps Beef Sticks are grass-fed beef sticks that are meant to be a healthier, high protein snack. While not a Costco-specific brand, Ramhold said, “The Costco subreddit has several users commenting on finding at least one stick in their package that seemed green from possible mold and therefore has to be tossed in the bin.”

She added, “Your mileage may vary on this product, though, and since the sticks are individually wrapped, you don’t have to worry about one contaminating the rest of the batch. Still, you might want to flip the bag over and see if you can view the sticks through the packaging to make sure everything looks as it should.”

In a separate Costco subreddit, shoppers shared some of the moments where buying fresh produce turned out to be cost-ineffective. 

Among the shortlist of items to avoid are strawberries, cucumbers and avocados, as shoppers complained they tend to go bad quickly.

While Kirkland signature dishwasher detergent has a large client base, it has also been the subject of complaints from those who have used it, said Jamie Penney, CEO of ShoppingFoodie.

“There have been numerous complaints from customers that the detergent does not dissolve correctly, leaving a film that makes dishes appear dirty. Some have also complained that the detergent makes them sick or makes their skin itch.”

How can you mess up a hard-boiled egg? Well, according to Eat This, Not That, more than 400 Reddit users have complained about them, deeming these to be everything from “pretty gross” to having a “weird flavor” which has been compared to plastic.
