You can maximize your shopping deals and maximize your credit card rewards by taking a trip to your local Costco to buy in bulk. 

This warehouse retailer has so many things besides groceries to indulge in. From luggage for an upcoming trip or new tires for your car, you can save money shopping for all kinds of items. So, yes, people love Costco…but some people also partake in some unsavory activities while wandering the aisles. 

Whatever you do, don't display these bad behaviors that employees and shoppers have reported seeing at the store.

Earn 2% cash rewards at grocery stores and Costco

The Wells Fargo Active Cash® Card(Rates and fees) is a powerful rewards card that allows you to earn unlimited 2% cash rewards on purchases — including on groceries, even at warehouse stores like Costco.

Making a meal out of samples

Costco is known for its amazing samples, which is great if you’re shopping and want to try one or two different things.

But Costco employees also say there are some people who abuse the offerings, with one employee admitting that he had customers tell him they only had a Costco membership to eat the free samples.

While we do admire the money-saving Costco hacks that people come up with, maybe making meals out of samples shouldn't be one of them.

Leaving a mess behind

Some of us have picked up a heavy mayonnaise jar only to have it slip and crash onto the unforgiving concrete Costco floor.

Having to contact a store employee because of the mess made can be embarrassing. However, employees report that more than a few customers have dropped, broken, and spilled things only to flee the scene without alerting anyone.

Smearing sticky fingerprints all over the store

The Costco food court is known for its delicious foods, especially sweets.

Yes, we love those sugary treats, but beware of the fallout if you eat one before you shop. It’s been reported that chocolate fingerprints have been spotted all over electronic displays.

Abandoning ice cream in the cracker aisle

We all might decide in the middle of shopping that we may not want something in our cart after all. But one Costco employee wishes customers wouldn’t leave frozen aisle items like ice cream on a shelf next to crackers.

Using crackers as a seat

Costco is a big store with many aisles and deals, and sometimes shoppers need a break. Taking a rest in one of the sample chairs in the furniture section is a good idea. Sitting on top of boxes of crackers, which at least one customer has done, is probably not.

Thinking Costco is a race track

Their warehouses are huge, their aisles are long, and shopping can sometimes get tedious. Perhaps in an effort to combat the boredom, some customers enjoy racing their carts through the rows at potentially dangerous speeds. This should only be done when no one else is in the store, which seems to be never.

Not putting your cart away

Voy_ager/Adobe Super Money-Saving Hacks Every Costco Shopper Should Know

One of the excellent things about the Costco parking lot is that some may have more cart areas than your local grocery store. Despite this, there are customers who insist on abandoning their carts in the middle of the lot instead of wheeling it to the cart return.

Hovering over employees for the freshest muffins

Everyone loves the freshest muffins at Costco, but apparently some customers really want to make sure they get the latest and greatest. One employee shared that customers would hover over him when he was stocking the baked goods, and then they’d snatch the newest packages from his cart.

Stealing the condiments

Hot dogs are delicious with all the extras, and Costco certainly has plenty of add-ons like pickles, onions, and relish in the food court. One customer was observed at the free condiments area filling up a bag with all of the onions offered and walking away.

Get a protection plan on all your appliances

Did you know if your air conditioner stops working, your homeowner’s insurance won’t cover it? Same with plumbing, electrical issues, appliances, and more.

Whether or not you’re a new homeowner, a home warranty from Choice Home Warranty could pick up the slack where insurance falls short and protect you against surprise expenses. If a covered system in your home breaks, you can call their hotline 24/7 to get it repaired.

For a limited time, you can get your first month free with a Single Payment home warranty plan.

Returning a tree after Christmas

Costco has a very generous return policy, and in most cases, you don’t even need a receipt. But one customer may have taken it too far when they returned a Christmas tree the day after Christmas, complete with dried branches and missing needles.

And yes, Costco stocks Christmas trees, which may surprise some people. A holiday tree is fairly typical compared to some of the bizarre Costco products on the shelf.

Bottom line

Costco is a wonderful place to shop and eat — and people-watch. Perhaps you've spotted some jaw-dropping moments while shopping, or maybe had your own slip when your behavior wasn't the best (we've all been there).

Sure, we all want to beat inflation costs, and there are plenty of ways to do that. But being a jerk shouldn't be one of them.
