Walk into any Costco around dinnertime and you can smell it before you see it. The rotisserie chicken. Five bucks, still warm, big enough to feed a whole family with leftovers for lunch. It might be the single most famous thing in the entire warehouse, and Costco sold more than 157 million of them worldwide in fiscal 2025. So it says a lot when employees, longtime members, and a stack of fresh lawsuits are all telling people to think twice before grabbing one on autopilot.
The chicken gets most of the attention, but it is not the only thing insiders quietly steer shoppers away from. Some items taste worse than they used to, some are just impulse traps built to get you spending, and a couple are flat-out worse deals than what you would find down the street. Let’s go through the ones worth leaving on the shelf.
The $4.99 Rotisserie Chicken Everyone Grabs Without Thinking
This is the big one. The $4.99 chicken has been Costco’s ultimate grocery hack for years, and the company keeps the price frozen even while everything else in the store creeps up, because it works as a loss leader that pulls people through the door. Two separate lawsuits filed in early 2026 have knocked some of the shine off it.
The first, filed in San Diego federal court in January, came from two California shoppers who say Costco advertised the chicken as having no preservatives while it actually contained sodium phosphate and carrageenan. Both additives are legal and approved, but the suit argues the “no preservatives” wording gave buyers the wrong idea. Costco has since pulled the signage and now says it uses both ingredients to keep the meat moist and consistent while it cooks. It moved to dismiss the case in June, calling it fatally flawed.
The second lawsuit landed in Seattle in February. It centers on Lincoln Premium Poultry in Fremont, Nebraska, the plant Costco built and owns to supply its own birds. The 37-page complaint claims the plant landed in the USDA’s worst rating, Category 3, in 56 of 65 reporting periods for whole birds since 2019, and 18 of 65 for chicken parts. The original plaintiff was replaced in May 2026 by five other shoppers, who say Costco never told them about the plant’s salmonella record and that they paid full price for a bird they would have thought twice about. Whatever a court eventually decides, the value pitch is exactly why so many people buy it, and the trust in that pitch is what these cases are chipping away at.
The Chicken Bake That Is Really a Sales Trap
Christina Polovina, who identified herself as a Costco manager in a Quora post back in 2020, laid out why she tells people to skip the food court Chicken Bake. It is that dense tube of crispy dough stuffed with chicken, bacon, cheese, and Caesar dressing, then dusted with Parmesan. It runs 770 calories by Costco’s own count, but her bigger point was about your wallet.
According to her, the cheap food court stuff exists mostly to get you inside and keep you wandering. As she put it, you come for a Chicken Bake and walk out with a TV on coupon you suddenly cannot pass up. The snack is bait. That $1.50 hot dog and the Chicken Bake are doing their job the second you decide to “just look” at the electronics aisle on your way out.
Kirkland Batteries That Leak Before You Even Use Them
Kirkland batteries look like a no-brainer. Giant pack, low price, decent brand reputation. But they show up again and again on lists of stuff shoppers regret buying in bulk. The complaint is almost always the same, and it is a bad one: they leak.
One shopper wrote online that theirs always leak after a year or two, and that no other batteries they had bought anywhere else did that. Another said a pack leaked before it was even opened. Worth knowing what this is and is not: there is no recall and no lab testing behind it, just a steady drumbeat of one-star reviews. The ten-year date on the pack is unused storage life, not a promise about a battery sitting in your remote. When a battery leaks inside a remote, a flashlight, or a kid’s toy, it can wreck the whole thing. Saving a few bucks up front is not worth replacing a device you liked.
The Boneless, Skinless Chicken Breasts People Call Funky
Raw chicken is another spot where the bulk deal does not always pay off. Plenty of members swear by Costco’s meat department, but the boneless, skinless chicken breasts get called out constantly for weird texture. Shoppers have straight-up nicknamed it “funky chicken.”
Shoppers usually blame water chilling, though the texture they are describing is more likely woody breast, a muscle condition that turns the meat spongy and shows up across the whole poultry industry rather than at any one store. When you are cooking for a crowd and the texture is off across a whole giant pack, that is a lot of dinners you are stuck with. A lot of people say they buy their chicken elsewhere and only come to Costco for the stuff they trust.
Protein Bars You Buy in a 20-Pack and Regret Instantly
Protein bars are a classic bulk-buy trap because you are committing to a mountain of them before you have tasted a single one. That is a gamble, and shoppers say it goes wrong a lot. One member described buying a case of a brand they had never tried and said nobody in the house could finish a single bar.
Someone else made a sharp point in the same discussion: ever notice Costco is happy to hand out samples for cheese, pizza rolls, and juice, but almost never sets up a taste test for the protein bars? Take that for what it is worth. If you want to try a new bar, grab a single one somewhere first. Do not buy 20 of a flavor you have never tasted.
Frozen Items That Fell Off a Cliff
The freezer aisle is where a bunch of once-loved Costco products quietly got worse. The frozen Kirkland Chicken Bakes take the hardest hits. They barely resemble the food court version, and one buyer described the chicken inside as super sketchy and gray, with a stingy, flavorless filling wrapped in a crust that somehow manages to be both too thick and limp instead of crisp.
Tyson Crispy Chicken Strips and Kirkland Pepperoni Pizza drew steady complaints about taste and texture in member reviews too. Junior’s Mini Cheesecakes got flagged for a chemical flavor, though results seem to swing by region and by person. The smarter move on that last one is skipping the frozen box and grabbing the bakery’s fresh Kirkland cheesecake instead, then adding your own fruit on top. Before you commit to any big frozen box, it pays to read a few reviews first.
Pre-Cut Fruit Trays
Pre-cut fruit trays feel like the perfect party shortcut. They are also one of the most complained-about grab-and-go items in the store. There is an entire online thread titled “Beware the pre prepped fruit trays,” which tells you how many people got burned.
Buyers keep reporting a fermented, slightly off taste and mushy textures across more than one purchase. That is the problem with pre-cut fruit anywhere: it starts breaking down the moment it is sliced, and you cannot see how long it sat before it hit the case. A whole pineapple and a bag of grapes cost less and taste fresher. It just takes ten extra minutes with a knife.
The Tire Center Employees Say to Shop Around
This one comes straight from people who worked there. A former employee who did everything from pushing carts to member services said the tire center is often not worth the trip, because the selection is thin and you can usually find the same tires cheaper if you check around.
Costco’s own policy page says it does not price match on tires, though it will adjust the price within 30 days if the same tire goes on sale there. A former tire center worker added that in their region the sticker price per tire ran a little higher than nearby competitors. Sometimes the installation and warranty package still comes out ahead, and sometimes it does not. The takeaway is simple: get one competing quote before you assume the warehouse automatically wins. On tires, it does not always.
So What Do You Actually Skip?
If you cut just one thing out of your cart, make it the item sitting at the center of two lawsuits and a wall of employee side-eye: the $4.99 rotisserie chicken. It is the most popular product in the building, which is exactly why the questions around it matter so much. Everyone buys it without a second thought, and “without a second thought” is the habit worth breaking.
The rest of the list is really about the same idea. Costco is fantastic for the things it is fantastic at, but bulk pricing tricks your brain into thinking every deal is a good one. The batteries, the funky chicken breasts, the untested protein bars, the sad frozen Chicken Bakes, and the pre-cut fruit are the spots where the size of the package hides a weak product. Buy the stuff Costco truly nails, and let someone else gamble on the rest.
