Grocery Store Rewards: What Counts for Amex and Chase?

You bought milk, eggs and vegetables. Your budget calls the purchase groceries. Your credit card may not.

Once you know which purchases qualify, use our cash-back cap guide to plan spending after a limit. For the current seasonal comparison, see Chase Freedom Flex Q4 groceries vs. dining.

Grocery store rewards depend on the issuer’s category rules and the transaction information it receives—not simply the food in your cart. Before choosing a grocery card, separate your total food spending from the portion likely to qualify.

Where Grocery Store Rewards Count: Walmart, Target, Costco, ALDI and Trader Joe’s

Amex names ALDI and Trader Joe’s as examples in its U.S. supermarket guidance, which excludes superstores and warehouse clubs. Chase’s grocery definition covers supermarkets and smaller grocery stores, with exclusions for clubs, discount stores and certain specialty merchants. The Chase column reflects general category definitions, not a promise of an active bonus. Check the exact offer for named merchant exclusions.

“Excluded” here means excluded from the category named in the column. It does not mean the purchase earns no rewards under every card or promotion. Likewise, an eligible merchant still requires a card with that benefit, available capacity under any cap, and satisfaction of the offer’s other conditions.

Costco acceptance comes first. Costco’s U.S. payment policy lists Visa credit cards for warehouses; Costco.com also accepts Mastercard. American Express credit cards are not listed as accepted in either channel. Check the policy for debit cards and other methods. Payment acceptance does not change the warehouse-club category exclusion.

*Dated example, separate from the standing rules: Chase’s October 1–December 31, 2026 grocery promotion expressly excludes Walmart and Target. That promotion does not establish eligibility for future offers.

Why Buying Food Is Not Enough

A useful way to think about eligibility is three separate questions: Can I pay with this card? Does this transaction fit the card’s bonus category? Is the bonus currently available on my account? A “yes” to one is not a “yes” to all three.

A merchant category code (MCC) identifies a merchant’s principal type of business. Issuers group merchant codes into reward categories. As Chase’s rewards agreement explains, a store that appears to fit a category may use a code outside it. That is why the posted rewards result matters more than your shopping-list label.

That creates a practical limit on any online merchant list. A list can show official exclusions and issuer-named examples. It cannot honestly certify every register, location, third-party checkout or future transaction without evidence. Treat an individual success report as a clue to investigate, not a promise.

Online Grocery Orders Are a Separate Check

An order placed through a supermarket website, a delivery platform and an in-store checkout may not follow the same payment path. Before changing your shopping routine, identify who actually submits the charge and which category your card rewards.

Chase says grocery delivery merchants qualify when classified as grocery stores. For Amex Blue Cash Everyday, an eligible online supermarket order uses the supermarket category; it does not add an online-shopping bonus on top. Paying with a phone in a store is not an online-retail purchase, which matters when a card has a separate online-retail reward.

Also separate rewards from service economics. A delivery fee or higher item price is part of the cost even if the charge earns a bonus. Earning an extra $3 is not an improvement if you paid $8 more to use that checkout route.

Your $800 Food Budget May Not Be $800 of Bonus Spending

Imagine a household spends $800 a month: $350 at an eligible supermarket, $250 at a warehouse club and $200 at a superstore. Under a hypothetical supermarket-only category, just $350—or 43.75% of that food budget—is eligible.

Calling the entire $800 “groceries” in a budgeting app overstates the eligible amount by $450. Build your card comparison from the $350 figure first, then evaluate the remaining purchases separately.

This is why the store split comes before the card recommendation. Someone who buys most food outside the eligible category may get less value from a supermarket specialist than a person with a smaller budget spent entirely at qualifying stores.

Common Edge Cases to Check

• Whole Foods and Amazon Fresh: Amex lists Whole Foods as an example. Do not transfer that result to every Amazon-branded checkout; check the merchant and card terms.
• Instacart and other delivery platforms: Verify the billing merchant and the category that your specific card rewards.
• Walmart.com grocery pickup: Ordering online does not automatically override a named merchant exclusion.
• Drugstores and dollar stores: A food aisle alone is not proof of grocery eligibility.
• Gift cards at supermarkets: Check eligible-purchase exclusions separately; supermarket classification does not guarantee that every transaction type qualifies.
• Specialty food shops: Amex excludes examples such as bakeries and butchers. Apply your own issuer’s definition rather than a generic “food” label.

How to Check Your Own Store

1. Read the exact category name. Grocery stores, U.S. supermarkets and online grocery can have different rules.
2. Check exclusions before shopping. An express exclusion should outweigh anecdotal reports.
3. Use a small purchase you already need. Avoid a large experiment made only to test rewards.
4. Wait for rewards to appear. A pending merchant description alone does not confirm the bonus.
5. Inspect the actual rewards detail. Compare rewards with the purchase amount and allow for separately displayed bonus entries.
6. Ask the issuer about a mismatch. Keep the receipt and transaction date. Ask about the specific charge, rather than whether the entire chain “always counts.”

A successful test supports using that same payment route, but it is not permanent insurance. Recheck after a change in checkout method, merchant processing or program terms.

Common Questions

Does buying only food at a superstore change the category?

Do not assume so. Plan around the issuer’s stated merchant rules, rather than expecting an itemized receipt to override an exclusion.

Does a warehouse-club exclusion make a grocery card useless?

No. It changes how much of your budget qualifies. A category card may still help with supermarket purchases while another accepted card handles the rest. Compare the extra dollars with any fee and the effort involved.

Can I use another issuer’s merchant list as proof?

No. It may be a research starting point, but the card’s own rules and transaction results control the practical decision.

The Bottom Line

Choose a grocery card for the stores and payment methods you actually use. The highest advertised rate is only useful on spending that qualifies—and only while the relevant bonus remains available.

Next, compare the wider options in CardTuned’s groceries-and-dining guide, then compare cards using only the spending likely to qualify.
