Costco can seem like a magical place with a delicious food court and tasty samples. It could also be a stressful shopping trip if you go on the wrong day or show up at the wrong time.

Whether you’re a regular or a new member, here are some surprising things you may not know about your favorite warehouse retailer as well as some genius Costco hacks.

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.

New cardholders can also earn a one-time cash rewards bonus — $200 cash rewards bonus after spending $500 in purchases in the first 3 months!

If you’re looking for a powerful rewards card that offers an extended intro APR period, look no further, the Wells Fargo Active Cash® Card checks that box too!

This card also offers an intro APR of 0% for 15 months from account opening on purchases and qualifying balance transfers (then 20.24%, 25.24%, or 29.99% Variable). Which is great for someone who wants a break from high interest rates, while still earning rewards.

The best part? There's no annual fee.

You don’t need a membership to shop

Costco is great if you have a membership, but there are some things you can still purchase even if you aren’t a member. 

You can get eye and hearing tests at many stores or have the Costco pharmacy fill your prescriptions, for example. It's a great way to keep more money in your bank account for some, normally, costly health items.

Some states prohibit the sale of alcohol to only clubs or members of an organization, so you may be able to grab supplies for your next party at Costco prices without a Costco card.


Get meds for your pets

In addition to medication for humans, Costco can also get you a deal on medication for your pets.

Costco’s Member Prescription Program, which is available to members, offers discounts on common human medications, but it also covers common pet medications like Heartgard for your furry friends.

Don’t shop on Mondays

You may think the beginning of the work week is a good time to head to your local Costco. After all, it’s better than dealing with the weekend rush, right?

But you might be surprised to learn that Mondays are one of the busiest days at Costco because other shoppers have the same idea as you.

If you’re on a budget, you may like making a meal out of Costco samples as you shop. Or perhaps you just want to test an item before you buy it in bulk.

Kirkland Signature may be hiding a name brand

Costco, like other retailers, has its own in-store label, and Kirkland Signature items are better than you might expect in some cases. And some of your favorite brands may be behind the Kirkland Signature name.

Kirkland Signature products may or may not be better than the name brand, so it might be a good idea to try different items to find your favorites.

It’s international

Costco warehouses aren’t just an American destination. Among its international locations are 40 stores in Mexico, 29 in the United Kingdom, 15 in Australia, and even one in Iceland.

In 2022, it opened new warehouses in Japan, Spain, France, and China along with additional stores in the U.S. The company reports it has a total of 875 warehouses worldwide.

It has a lot of members

In May, Costco reported that it had 116.6 million cardholding members. And while membership does have its perks, including great deals on bulk items, there are some things you can get without a membership like vision and hearing tests. 

You can also take advantage of the Costco food court deals without a member card.

Costco has warehouse space

Sure, you may walk into your local Costco and think it’s big. But how big? Costco reports that the overall space in its warehouses combined is 120 million square feet. And you thought your local Costco took a long time to walk through.

Costco sells rotisserie chickens at a loss

Costco’s rotisserie chickens are a great bargain, but at $5 per chicken, Costco actually takes a loss on them. Costco prefers to use them as a way to get customers in the door even if it means they don’t make a profit on them.

The chickens traditionally warm the back of the store to make you walk through the warehouse and see all the products before you get there.

Pro tip: Only certain credit cards are accepted at Costco. Make sure you have one that will work as well as one that can help you earn rewards like cash back.

Bottom line
