Can you buy gift cards at grocery store to receive a higher reward rate?
(I agree with the answers above; would just like to make a couple of additional points.) It's a good and simple strategy to try it out with a small amount as suggested by @JoeTaxpayer♦. It's also generally safe to assert that card issuers currently don't receive or actively look at itemized transaction details. But that does not mean they cannot in the future. Some stores utilize level 3 data processing, which tells the card issuers exactly what you bought in a transaction. An example of level 3 data being utilized to reject rewards is with Discover, which announced a 10% cashback reward for any transactions made with Apple Pay last year. It later introduced an additional term to exclude gift card purchases. And this has been verified to be effective - no more reward on gift card purchases; clawback of cashback on existing gift card transactions. As far as I know, Amex does receive and look at some level 3 data retrospectively. That does not necessarily mean they will claw back your cashback after initially rewarding the 6%. But it might show up if you ever trigger an account review, and be used as evidence of your "abuse" of the program (which BTW is defined rather subjectively). There has been many cases of account shutdowns because of this. Card issuers are also trying to do a better job preventing "abuses" by proactively setting caps on rewards (as opposed to closing those accounts afterwards and taking the rewards away altogether). Given the trend in recent years, I have to speculate that at some point the card issuers would put clear language in the terms against gift card purchase and enforce it effectively (if they haven't already). This reward game is constantly changing. It's good while it lasts. Just be prepared and don't get surprised when things go south.
