If you like your credit card rewards in cash, and a lot of it, then the Citi® Double Cash Card – 18 month BT offer and the Blue Cash Preferred® Card from American Express should be on your radar, if not in your wallet.
These cards offer some of the highest cash-back rates available, although they structure their rewards quite differently:
The Citi® Double Cash Card – 18 month BT offer is a flat-rate card, meaning you get the same rate on every purchase. And what a rate it is: 2%, broken down as 1% cash back on every dollar you spend and another 1% on every dollar you pay back. Sweetening the deal, the annual fee on this card is $0.
The Blue Cash Preferred® Card from American Express offers tiered rewards, meaning you get a higher rate in certain categories. The card gives you 6% cash back at U.S. supermarkets on up to $6,000 a year in spending (then 1%); 6% cash back on select U.S. streaming subscriptions; 3% cash back at U.S. gas stations and on transit (including such things as taxis, rideshares, parking, tolls, trains and buses); and 1% cash back on all other purchases. The catch? It has an annual fee: $95. Terms apply (see rates and fees).
Look to your grocery bill
The signature feature of the Blue Cash Preferred® Card from American Express is the 6% cash back at U.S. supermarkets on up to $6,000 a year in spending. And for most people, this spending will be the deciding factor between these cards.
If you don't spend much at supermarkets, you're going to have to spend a lot of money on gas, transit and streaming to make up for the annual fee — and make up the difference between this card and the Citi® Double Cash Card – 18 month BT offer. Really, if you don't spend much at the supermarket, you have no business carrying the Blue Cash Preferred® Card from American Express at all.
But let's say you've got a lot of mouths to feed. Counting supermarket shopping alone, and taking into account the annual fee and the $6,000 rewards cap, you would have to spend at least $1,710 a month ($20,520 a year) before the annual rewards on the Citi® Double Cash Card – 18 month BT offer would surpass those on the Blue Cash Preferred® Card from American Express. That's a lot of peanut butter.
There's more to life than groceries, though. Transportation, dining out, dog grooming, traffic tickets, patio furniture — it all adds up. If the bulk of your ongoing expenses are incurred outside the supermarket aisle, the 2% everyday rewards rate on the Citi® Double Cash Card – 18 month BT offer is clearly better than the 1% rate on the Blue Cash Preferred® Card from American Express. The AmEx card's 3% rewards at U.S. gas stations and on transit could mitigate the damage a little — but remember, that annual fee still has to be paid whether you rack up big supermarket rewards or not.

New cardholder perks
The Blue Cash Preferred® Card from American Express comes with a welcome bonus that takes some of the sting out of the hefty annual fee. As AmEx puts it: Earn a $350 statement credit after you spend $3,000 in purchases on your new Card within the first 6 months. Terms Apply.
The standard offer on the Citi® Double Cash Card – 18 month BT offer does not include a sign-up bonus — but, hey, a $0 annual fee doesn't sting nearly as much.
Although the Citi® Double Cash Card – 18 month BT offer does not usually come with a sign-up bonus, the card currently has this offer in effect: For a limited time, earn $200 cash back after spending $1,500 on purchases in the first 6 months of account opening.
With any rewards card, it's best to pay your balance in full every month to avoid running up interest, which can quickly wipe out the value of your rewards. But if you need to carry a balance as a new cardholder, both cards give you a bit of a break. For the Blue Cash Preferred® Card from American Express, you get an introductory APR of 0% intro APR on Purchases for 12 months, and then the ongoing APR of 16.24%-26.24% Variable APR.
Citi's card offers a long 0% period, but it's only for balance transfers: 0% intro APR on Balance Transfers for 18 months, and then the ongoing APR of 16.24%-26.24% Variable APR.
If you choose to transfer a balance onto the Citi card, you should be aware of what will happen. When you carry a balance on a credit card from month to month — even one transferred at 0% interest — you'll get no grace period on purchases. You'll pay interest on purchases from the day they hit your account.
Why not carry both?
If you're dead-set against paying an annual fee on a credit card, then your choice is easy. The Blue Cash Preferred® Card from American Express has one of the steepest fees of any consumer cash-back card, while the Citi® Double Cash Card – 18 month BT offer charges you precisely zip.
On the other hand, if you've got a family and you're spending, say, $700 a month at the supermarket, the Blue Cash Preferred® Card from American Express is offering you a lot of free money for a space in your wallet, even after the fee.
At this point, you might be thinking: "If only I could get the high rewards rates on the AmEx card's bonus categories and the Citi card's 2% rate on everything else." Well, uh, you can. A quick-and-dirty way to optimize your cash-back rewards is to simply carry both cards. Pull out the Blue Cash Preferred® Card from American Express at the supermarket, the gas station and when you're paying for streaming or transit. For everything else, use the Citi® Double Cash Card – 18 month BT offer. Plenty of people do just that.
Others prize simplicity and would prefer to carry just one card for everyday use. If that's you, start banging away at the calculator and make your pick accordingly.
