Secrets Costco Doesn't Want You To Know

What can't you buy at the warehouse nirvana Costco? Famed for its generous treatment of employees, low prices, and massive packages, members flock to Costco stores to sample a plethora of gratis nibbles while they stock up on everything from gallon vats of organic coconut oil to Disney vacations (And if the vacation doesn't go so well, you can even buy a casket).

But there's a lot more to Costco than its giant aisles, generous samples, and tasty $1 hot dogs. In fact, there's quite a lot about this members-only warehouse club that the company would probably rather you not know. From hacks for saving even more money to little-known services offered by the company, there are many under-the-radar ways to optimize your Costco experience. Lucky for you, we're here to spill all the secrets Costco has tried to hide. Here are the secrets Costco doesn't want you to know. 

In comparison to most retailers, Costco's return policy is pretty sweet. Costco's satisfaction guarantee covers a majority of the merchandise it sells, meaning even that sensible navy blue parka you bought last year and removed the tags from can be returned for a full refund. No receipt? No problem — the customer service desk can look up the purchase for you using your membership number. Opened food items can even be brought back to the store, which makes a great case for trying out something new.

There are, of course, a few exceptions to the rule. Costco is legally prohibited from accepting returns on alcohol and cigarettes in most states. It is also free to decline a return on a "limited life" product, like batteries, and requires an inspection of diamonds over a carat in weight before issuing a refund. Major electronics, like appliances, televisions, and cellular phones must be returned within 90 days of purchase.

A return policy this forgiving no-doubt attracts its fair share of mooches who try to push the envelope. Some of the most insane returns Costco employees have ever seen attempted include opened packages of underwear, a 15-year-old pressure washer, and plants that died after being neglected. There was even the woman who brought back a piece of fish she'd had in her freezer for 13 years — and successfully returned it.

Ever wondered why the toilet paper and laundry detergent at your local Costco store always seem to be placed in a new aisle? This tactic is completely intentional, and known by the top brass of Costco as the "treasure hunt," according to Fast Company. This strategy is a devious attempt by Costco to make you buy more products that you weren't planning to pick up when you walked into the store. The search for your intended "trigger" items is going to lead you on a carefully orchestrated path past seasonal items, clothing, bestselling cookbooks, and of course, those tantalizing food samples. 

About 1,000 of Costco's items on any given day may be goods only available temporarily, so it's up to you if they are bargains that are truly too good to pass by. The best advice for avoiding temptation? Make a shopping list, and stick to it.

When the above video leaked in June of 2015, depicting the inhumane and vile conditions at an egg factory farm that supplied eggs from caged hens to Costco, people got fired up — including celebrities like Bill Maher and Brad Pitt. Referencing a vague promise Costco had made in 2007 to transition to cage-free eggs in all of its stores, the celebs argued that Costco was taking too long to actually implement the switch.

Costco responded to the backlash with a renewed commitment to sourcing cage-free eggs, promising work toward being completely cage-free. But it seems even its cage-free operations have been met with some scrutiny. The New York Times reported in October of 2016 that an undercover video obtained by animal rights group Direct Action Everywhere showed that the conditions in a California cage-free facility that supplied eggs for the Costco Kirkland brand were not all that much better than a caged factory farm. The video, depicting chickens roaming in filth and walking over dead carcasses, was criticized by the egg producer as "being staged for production effect." Costco, in response, stated, "We have reinspected the barn and other operations of this supplier, and based on these inspections and prior audits, we are comfortable with the animal welfare aspects of the operation."

Costco eggs are more expensive than grocery store eggs as well, so you might want to think twice about picking up your eggs from Costco.

Members' love of the warehouse giant makes Costco one of the top three retailers in the US, according to a 2022 list from the National Retail Federation. But with that much going for it, there are bound to be some haters. What are the chief complaints most often heard about Costco? According to Consumer Reports, many members aren't crazy about Costco's limited selection, long checkout lines, customer service, and absence of fitting rooms.

Costco does not offer plastic bags, or bags of any kind, at the register. Customers can opt instead to reuse the cardboard boxes found near the checkout aisle, but this policy can become frustrating not only for shoppers, but also for employees, who are pressured to keep boxes at the ready. Costco, unlike competitor Sam's Club, does not offer delivery or installation services, which can be quite the dilemma when you've just nabbed that outdoor patio set and gazebo deal before your Memorial Day barbecue.

Costco is the best place to shop if you want a good deal on grocery items. But those savings do come at a cost as a yearly Gold Star membership will cost you $60 a year, and an Executive Membership will set you back $120 a year (via Costco). While you'll more than make up the cost of the membership if you shop frequently at Costco, it turns out there are often Groupon deals that can help reduce that yearly membership cost even more.

As of publication, Groupon is currently offering a Costco membership deal that gives you a $10 Costco shop card when you sign up for a Gold Star Membership, or a $20 Costco shop card if you sign up for a new Executive Membership. Executive Members also have access to a rewards program where they earn up to 2% on qualifying purchases, with a value of up to $1,000. That's a lot of savings. And according to the Penny Hoarder, Costco has had even better Groupon deals in the past, like a free 72-count pack of Kirkland Signature AA batteries valued at around $20, a free variety 4-pack of Kirkland Signature disinfecting wipes, $10 off meat purchases, and $25 off an order of $250 or more on Costco.com. So if you're finally about to pony up for a first-time Costco membership, make sure you check for membership deals beforehand.

If you've ever bought a bigger electronics item from Costco like a television or kitchen appliance, you already know you got yourself a great price. But what you might not realize is that Costco provides free tech support for the lifetime of most of the electronics and appliances it sells. That's right: free tech support. When it comes to membership perks, this might be the motherlode.

It's called Costco Concierge Services and it's automatically included in your Costco membership. So if you need help installing a new appliance or troubleshooting an issue, know that Costco has got your back. You can even speak directly to a tech support rep to walk you through whatever questions or issues you're having. Apparently, there is hardly ever a wait to speak to anyone. Plus, Costco extends the warranty on most products up to two years. With all these added perks, it seems insane to buy electronics and appliances anywhere BUT Costco.

The low prices and bulk sizing aren't the only reason to get a Costco membership. One of the most iconic and fun reasons to shop at Costco is to partake in all the free samples handed out throughout the store. And while you might feel guilty or awkward going back for seconds or even thirds of a sample you particularly liked, know that Costco policy allows for customers to take as many free samples as they like (via CBS News.) So go ahead, live a little.

Of course, an unlimited free sample policy isn't an invitation to be a jerk. One Costco Sample Person took to Reddit to share about a time a teenager took nine trays of Ferrero Rocher candies, which was about $50 worth of free product. While company policy kept the free sample contractor from stopping him, let this be a PSA that this is pushing it and at the very least, and you may be judged and talked about on Reddit.
