As a savvy Costco shopper, you‘re always on the lookout for ways to maximize your savings. After all, that‘s one of the biggest perks of being a Costco member – the ability to score unbeatable deals on everything from household essentials to high-end electronics.
But when it comes to payment methods, the options can get a bit confusing, especially when it comes to using your trusty Discover card. Can you really use it to pay for your Costco purchases, or are you stuck with a more limited selection?
Well, my friend, you‘re in luck. In this comprehensive guide, we‘re going to dive deep into the world of Discover cards and Costco to give you all the details you need. By the time we‘re done, you‘ll know exactly where and how you can (or can‘t) use your Discover card at the warehouse giant.
Can You Use Discover at Costco In 2025?
Let‘s start with the big question – can you actually use your Discover card at Costco in 2025? The short answer is… it depends.
Does Costco Accept Discover Cards?
When it comes to in-store and gas station purchases at Costco, the answer is a resounding no. Costco has an exclusive partnership with Visa, which means they only accept Visa credit cards for these types of transactions.
This hasn‘t always been the case, though. Up until 2016, Costco shoppers were limited to using American Express cards exclusively. But that all changed when the retailer announced a long-term co-brand credit card agreement with Citi and Visa.
Under this new deal, Costco members could now use any Visa credit card, including the Costco Anywhere Visa Card by Citi, to make purchases both in-store and at the gas pumps. But unfortunately, Discover, Mastercard, and American Express were left out in the cold.
"Costco is one of the biggest retailers that don‘t accept Discover cards, especially in-store," explains Marques Thomas, founder of QuerySprout.com. "This is because Costco has an exclusive partnership with Visa; therefore, the company only takes Visa credit cards."
Why Isn‘t Discover Accepted at Physical Costco Stores?
So, why the hard line against Discover cards? It all comes down to cold, hard cash – or rather, the fees associated with processing different credit card transactions.
You see, credit card networks like Visa, Mastercard, and Discover all charge merchants a percentage-based "interchange fee" every time a customer uses their card. And these fees can vary quite a bit between the different networks.
According to industry data, Discover and American Express tend to charge higher interchange fees compared to Visa. And for a massive retailer like Costco, those extra costs can really add up quickly.
"Discover, just like American Express, is more costly for merchants," Thomas explains. "Overall, this is why retailers like Costco switched to Visa to take advantage of the lower merchant fee and the more extensive credit network."
By limiting in-store and gas station payments to Visa cards only, Costco is able to significantly reduce its credit card processing expenses. And those savings can then be passed on to members in the form of even lower prices.
Can You Use Discover at Costco Gas Stations?
Unfortunately, the Discover card restrictions don‘t just apply to in-store purchases at Costco. They also extend to the warehouse club‘s gas stations as well.
According to Costco‘s website, the only payment methods accepted at their fuel centers are Visa cards, the Costco Anywhere Visa Card by Citi, Costco Shop Cards, and most PIN-based debit cards. Discover, Mastercard, and American Express are all off the table.
So if you‘re a Discover cardholder who regularly fills up at Costco, you‘ll need to either use a different payment method or head to a non-Costco gas station instead. It‘s a bit of a bummer, but those Visa-exclusive policies are pretty ironclad.
Can You Use Discover at Costco.com?
Now, the good news is that Discover cards are accepted for online purchases through Costco.com. In addition to Discover, you can also use Visa, Mastercard, the Costco Anywhere Visa Card by Citi, Costco Shop Cards, and most PIN-based debit cards to pay for items on the Costco website.
So if you prefer the convenience of online shopping, you can absolutely use your Discover card to make purchases from Costco.com. Just keep in mind that it won‘t work for in-person transactions at the warehouse clubs or gas stations.
According to Costco‘s customer service, the retailer accepts the following payment methods on their website:
- Discover Cards (including Diners Club and JCB)
- Visa Cards
- Mastercard
- Costco Anywhere Visa Card by Citi
- Costco Shop Cards
- Most PIN-based Debit Cards
So while you may not be able to use your Discover card at the physical Costco locations, you can still take advantage of it for all your online shopping needs.
What Are Other Payment Methods Accepted at Costco Warehouses?
Since Discover cards are not accepted at Costco warehouses, it‘s important to know what other payment options are available. Here‘s a full rundown of the accepted methods:
- Costco Anywhere Visa Card by Citi
- All Visa Credit and Debit Cards
- Costco Shop Cards
- Most PIN-Based Debit Cards
- Cash
- EBT Cards
- Apple Pay, Google Pay, Samsung Pay
- Traveler‘s Checks
- Business Checks
- Personal Checks
It‘s worth noting that Costco does not accept American Express, Mastercard, or checks for in-store purchases. So if you have a credit or debit card from those networks, you‘ll need to use an alternative payment method when shopping at Costco warehouses.
Can You Use Discover Cards to Pay for Costco Travel?
In addition to in-store and online shopping, many Costco members also take advantage of the company‘s travel booking services through Costco Travel. However, when it comes to paying for vacation packages, hotel stays, and other travel arrangements, Discover cards are not an accepted payment method.
According to the Costco Travel website, the only credit and debit cards accepted are Visa and Mastercard. Costco Shop Cards can also be used to pay for travel bookings, but Discover, American Express, checks, money orders, mileage payments, and temporary Costco Anywhere Citi Visa Cards are not accepted.
So if you‘re planning a Costco Travel booking, be sure to use a Visa or Mastercard to complete your purchase. Discover cardholders will need to find an alternative payment option.
Conclusion: Maximizing Your Savings at Costco as a Discover Cardholder
In summary, while you can use your Discover card to make purchases on Costco.com, it is not accepted for in-store or gas station transactions at Costco warehouses. This is due to Costco‘s exclusive partnership with Visa, which allows the retailer to offer lower merchant fees and a more extensive credit network for its members.
To make the most of your Costco shopping experience as a Discover cardholder, be sure to have a Visa card, the Costco Anywhere Visa Card by Citi, or a PIN-based debit card on hand. And if you‘re booking travel through Costco, remember that Discover cards are not an accepted payment method.
By understanding Costco‘s payment policies and the available options, you can ensure a seamless checkout process and continue maximizing your savings as a savvy Costco shopper. After all, that‘s what being a member is all about – getting the best deals possible on the products and services you need.
So the next time you‘re stocking up at Costco, leave that Discover card in your wallet and reach for a Visa instead. Your wallet (and your bank account) will thank you!
