The Best Buy Credit Card works at Best Buy stores and Best Buy's website, but not at other retailers

The Best Buy Credit Card is a store card, which means it's issued by Citi and works only at Best Buy and Best Buy's online store. You cannot use it at Target, Walmart, Amazon, or any other retailer. If you try to use it outside Best Buy, the transaction will be declined.

Best Buy also operates Best Buy Mobile, which is a separate storefront inside some Best Buy locations. Your Best Buy Credit Card works there too, since it's part of the same company. But the card has no value anywhere else — not at gas stations, restaurants, grocery stores, or other electronics retailers like Micro Center or B&H Photo.

This limitation is the trade-off for the card's rewards structure. Because the card only works at one place, Best Buy can offer higher rewards rates there than a general-purpose card would. You get 5% cash back on Best Buy purchases (with some exclusions), but you get nothing on purchases elsewhere.

Key Takeaways

  • The Best Buy Credit Card works only at Best Buy stores, Best Buy.com, and Best Buy Mobile locations — not at any other retailer.
  • Transactions at other stores will be declined, so you cannot use it as a backup card outside Best Buy.
  • The card earns 5% cash back on most Best Buy purchases, but earns no rewards on anything bought elsewhere.
  • If you shop at multiple retailers, you will need a separate general-purpose credit card for non-Best Buy spending.

What happens if you try to use it somewhere else

If you attempt to use the Best Buy Credit Card at a store that is not Best Buy, the card will be declined at the point of sale. The merchant's system will not recognize it as a valid payment method because Citi has restricted it to Best Buy's merchant codes only. You will not be charged, and no partial transaction will go through.

This is different from a card that simply won't earn rewards elsewhere — the Best Buy card physically cannot process a payment outside Best Buy. The decline happens instantly, and you will need to use a different payment method to complete your purchase.

Best Buy purchases that do earn the 5% cash back

The 5% cash back applies to most items you buy at Best Buy, including electronics, appliances, computers, and accessories. It also applies to purchases on Best Buy.com. However, some categories are excluded from the rewards rate.

Best Buy excludes certain items from earning cash back: gift cards, mobile phone activation fees, services like Geek Squad protection plans (though some service purchases do earn rewards — check your receipt), and items purchased through third-party sellers on Best Buy's marketplace. Tax and shipping are not included in the rewards calculation either.

You earn 1% cash back on everything else you charge to the card, including those excluded categories. So you still get some return, just at a lower rate. The cash back posts to your account monthly and can be redeemed as a statement credit or transferred to a linked bank account.

Online shopping and the Best Buy app

The Best Buy Credit Card works on Best Buy.com at the same 5% cash back rate as in-store purchases. You can also use it in the Best Buy mobile app when you order for pickup or delivery. The rewards rate does not change based on how you shop — online, in-store, or through the app all earn the same percentage.

If you use the card to buy a gift card on Best Buy.com, that purchase itself does not earn cash back, but when you later use that gift card to buy something at Best Buy, the gift card purchase earns rewards at the normal rate. This is a common workaround if you want to earn rewards on a gift card purchase, though it requires two transactions.

Why Best Buy issued a store card instead of a general-purpose card

Best Buy chose to issue a store card through Citi rather than a co-branded card that works everywhere. Store cards let the retailer offer higher rewards rates because the card issuer knows all spending happens at one place — there is no risk of rewards bleeding into low-margin categories or competitors' stores.

The trade-off for you is that the card is useful only if you shop at Best Buy regularly. If you buy electronics once a year, the card probably is not worth carrying. But if you buy computers, phones, appliances, or gaming equipment multiple times a year, the 5% cash back can add up quickly. A $1,000 laptop purchase earns $50 in cash back, for example.

Best Buy also offers a Best Buy Visa card, which is a general-purpose card that works anywhere Visa is accepted. That card earns lower rewards rates (typically 1.5% to 3% depending on category) but works everywhere. Some customers carry both — the store card for Best Buy purchases and the Visa for everything else.

How the card compares to a general-purpose rewards card

A general-purpose card like the Chase Sapphire Preferred or the American Express Blue Cash Preferred works at any merchant and earns rewards across all spending categories. But those cards typically earn 2% to 5% cash back depending on the category, and many charge an annual fee ($95 to $550 depending on the card).

The Best Buy Credit Card has no annual fee and earns 5% at Best Buy, which beats most general-purpose cards in that category. But it earns nothing at other retailers, so if you split your spending across multiple stores, a general-purpose card might deliver more total rewards despite the lower rate.

The math depends on your spending pattern. If 50% or more of your annual purchases happen at Best Buy, the store card usually wins. If you spread your spending across many retailers, a general-purpose card is more useful — even with an annual fee — because you earn rewards everywhere.

Frequently Asked Questions

Can I use the Best Buy Credit Card at Best Buy's website on my phone?

Yes. The card works on Best Buy.com whether you access it from a computer, phone browser, or the Best Buy mobile app. The rewards rate is the same — 5% cash back on may be able to access purchases — regardless of how you access the site.

What if I buy something at Best Buy with a different card and then return it?

The refund goes back to the card you used to buy it. If you paid with a different card, the refund credits that card, not your Best Buy Credit Card. You do not earn cash back on refunds.

Does the Best Buy Credit Card work at Best Buy locations inside other stores?

Yes. Some Best Buy kiosks operate inside other retailers like Costco or airports. Your Best Buy Credit Card works at those locations and earns the same 5% cash back as a standalone Best Buy store.

Can I use the card to pay my Best Buy credit card bill?

No. You cannot use the Best Buy Credit Card to pay the Best Buy Credit Card balance. You must pay the bill using a bank account, another credit card, or check. Paying a credit card bill with itself is not allowed by any card issuer.

What if I move to another country — can I use the card there?

Only at Best Buy locations that operate internationally, which are very limited. Best Buy has minimal international presence, so the card will not work at most foreign retailers. Contact Citi before traveling to confirm whether any Best Buy stores exist in your destination.
