Costco vs. Sam’s Club Credit Cards Comparison: Which Is Better?

Written by |

Are you a wholesale club fanatic like money expert Clark Howard?

Costco and Sam’s Club offer tremendous benefits to customers that can save money that goes well beyond simply covering the annual membership fees.

Team Clark has a deep dive on the merits of membership to each in a comparison of the two popular wholesale clubs.

In this article, we’re going to assume that you’re a committed member to each club looking to take the next step: signing up for the co-branded credit cards.

Each card has its rewards for in-store purchases with your store of choice, but there’s value outside the wholesale club, too.

For example, you may be surprised to learn that both the Sam’s Club and Costco credit cards show up on our list of “best” for rewards on gas purchases.

Clark carries both cards in his wallet. Let’s compare to see if they’re also worth adding to yours.

Card Overview: Costco Anywhere Visa® Card by Citi

This card is good for getting 2% back on everything you spend at Costco, but it actually offers even better rewards for some common purchases you may make outside of the wholesale club.

You’ll be able to earn 4% back on gas or EV charging purchases for the first $7,000 per year.


And 3% back on popular spending categories like dining and travel.

Purchases at most cafes, bars, lounges and fast food restaurants will qualify for this bonus. Costco warns that some bakeries and restaurants located within retail stores could be excluded. For the travel reward, you can expect airfare, hotels, car rentals, travel agencies, cruise lines and Costco Travel purchases to qualify for the 3%. Travel purchases that may be excluded include timeshares and commuter travel.

The downside to earning rewards with this card is that redemption is a little bit rigid:

You get an annual rewards certificate along with your February credit card billing statement. Then you need to take the certificate to Costco. From there, you can redeem your certificate for Costco merchandise or cash. (It’s up to the discretion of the individual Costco location if the certificate can be redeemed for actual cash or a check.)

However, Team Clark’s Christopher recently detailed how Citi is allowing select customers to opt into a direct deposit of the funds if their rewards meet certain criteria. So this may be getting better.

Card Overview: Sam’s Club® Mastercard®

This card is good for the base-level Club members who will see 1% cash back at Sam’s Club, but it’s even better for those who pay the extra money to be Sam’s Club Plus members.

If you apply for this credit card with a Plus membership ($110 annual fee), you’ll see greater rewards opportunities.

In addition to perks like free shipping and access to pharmacy and optical services, you’ll also get increased cash back rewards.

Sam’s Club Plus members always get 2% back on qualifying pre-tax store purchases with a maximum reward of $500 per 12-month membership period.


But by using the Sam’s Club Mastercard, Plus members see a boost in their purchase rewards. Plus members earn an additional 3% by using their store-branded card.

So when you add those together, it can be worth up to 5% back on Sam’s purchases for Plus members.

Final Thoughts

If you are a Costco or Sam’s Club member, you can find value in having either of these co-branded credit cards in your wallet for in-store and online purchases.

You also may find that one of these cards offers better rewards for gasoline purchases than any other rewards credit card in your wallet.

Both present club members compelling cases to apply and use for purchases in and out of the wholesale club’s ecosystem.

But when it comes to picking between the two cards, it likely will take some evaluation of your personal spending habits.

Ask yourself these questions:

  • Do I shop at my wholesale club enough to justify applying for a co-branded credit card?
  • Would I also use this credit card for purchases like gasoline, dining and travel?
  • Which wholesale club do I frequent most often?
  • If it’s Sam’s Club, would upgrading to a Plus membership be worth the extra rewards opportunities?
  • Do I spend enough money at BOTH stores to consider applying for both cards?

The answers you give to these, in combination with the information we laid out in this article, are likely to help you decide on one, both or none of these co-branded rewards cards.
