The Citi Dividend 5% categories for the second quarter of 2023 being Grocery Stores and Drugstores. Both of these are easy to max out with ordinary purchases or gift card purchases.
Citi is different than the other cards in that you have a $6,000 annual cap rather than a $1,500 quarterly cap. Thus, you can get 5% back on up to $6,000 in this quarter, you can save the entire amount for a different quarter, or you can use part up each quarter.
