If you frequently shop at Costco, you know it’s easy to rack up a big purchase quickly buying vast quantities of items in bulk. Over an entire year, you could spend significant dollars at the popular warehouse club.

As with any big annual outlay of funds, we’re always on the lookout for ways to make sure those purchases earn as many rewards as possible.

Costco is unique in that not all types of payments or credit cards are accepted in-store. With that obstacle in the forefront, we’ll zero-in on the cards that do earn rewards at Costco to help you make your selection.

If you’re a Costco lover, which many shoppers are, you’re probably wondering which cards made our list. Let’s dig in and find out the best ways to earn more rewards at Costco.

How Does Costco Work?

Costco is an American-based warehouse retailer operating membership-based wholesale shopping clubs with hundreds of locations across 8 countries.

Retail locations offer members savings on things like groceries, clothing, household products, business and restaurant supplies, and travel services. You’ll also find a photo, auto, and optical center, as well as a pharmacy, located in each store.

You may also purchase products and services at Costco.com and at Costco gas stations.

A basic Gold Star or Business membership costs $60 per year, while a Gold Star Executive or Business Executive Membership costs $120 per year. Business memberships allow you to add additional people to your membership and purchase items for resale. Executive-level memberships, both personal and business, earn 2% rewards on eligible purchases, paid out annually.

Best Credit Cards for Shopping In-Store at Costco or Online at Costco.com

You won’t be able to use your American Express, Mastercard, or Discover-issued cards at Costco as the retailer accepts only Visa for in-store shopping. Let’s take a look at some of the best cards you can use for shopping in-store at Costco or online at Costco.com, and the associated card benefits.

Costco Anywhere Visa® Card by Citi

The Costco Anywhere card is an obvious choice for shopping in-store. The card earns well on specific everyday purchases, purchases at Costco, and at Costco.com. But there are a few drawbacks to the card.

Why We Like the Card for Shopping at Costco

• 4% cash-back at gas stations, including Costco, up to $7,000 in purchases each year, then 1%
• 2% cash-back at Costco and Costco.com

Why We Like the Card Overall

• 3% cash-back at restaurants and on travel purchases
• 1% cash-back on all other purchases
• No annual fee
• No foreign transaction fees
• Good anywhere Visa is accepted
• Shopping protections such as purchase protection and extended warranty

Costco Anywhere Visa® Business Card by Citi

It’s always good to keep business and personal purchases separate. Fortunately, in addition to the personal card, Citi offers the Costco Anywhere Business card.

Like the personal Costco Anywhere card, the Costco Anywhere Business card comes with the same bonus category earnings, redemption options, benefits, and no annual fee.

Also, like the personal Costco Anywhere card, you must have a Costco membership to be approved.

Drawbacks of the Costco Anywhere Card and Costco Anywhere Business Card

• No welcome bonus offer
• You must have a Costco membership to be approved for the card (at a cost of $60 to $120 per year)
• Cash-back earnings are paid out just once per year in-store

You can accept your cash-back earnings in the form of a store credit or cash.

Bottom Line: If you’re a frequent Costco shopper, either Costco Anywhere card could be a viable option for earning rewards when shopping at Costco. The drawbacks are minimal and since neither card charges an annual fee, if you receive value in excess of your membership fee, the card could be worthwhile.
