Earning rewards from your credit cards is a lot like earning interest on your investments. Cardholders should look for the highest returns possible considering the amount they spend and the type of merchants they frequent. They then need to balance these rewards against any fees assessed on their cards. The Blue Cash Preferred® Card from American Express offers as much as 6% cash back rewards for your spending at a time when many reward cards only offer 1%-2% cash back.

Preferred’s Cash Back Percentages   

Like many credit cards, customers earn 1% cash back on purchases from most retailers, but it is the bonus categories that make this card stand out. (All cash back is earned as Reward Dollars that can be used as a statement credit.)

3% cash back at US gas stations and select US department stores.

A whopping 6% cash back is earned from purchases from US supermarkets, not including warehouse or discount stores. How good is that? Let’s just say that some people were taking this discount so far that American Express recently imposed a $6,000 annual cap on eligible purchases. After earning $360 (6% of 6,000) in cash back from US supermarkets, cardholders will now earn just 1% on subsequent purchases.

Finally, new cardholders earn $100 in Reward Dollars after spending $1,000 within the first three months of opening their account.

Other Benefits

Because Blue is an American Express card, you can expect a wide range of other benefits beyond simple cash back.

  • The Return Protection benefit gives you up to 90 days to return a purchase, even if the merchant has a shorter time limit on refunds.
  • The card also extends an eligible product's warranty for an extra year, if the original warranty is less than 5 years.
  • You have the standard rental car loss and damage insurance that most cards offer. But in addition, you also receive access to a Roadside Assistance Hotline to help you find a tow truck or locksmith.
  • Cardholders receive travel accident insurance that covers any kind of common carrier transportation when paid for with their card.
  • Finally, there is a 24/7 Global Assist hotline that can provide help when you are traveling.


There is a $75 annual fee for this card and a 2.7% foreign transaction fee on all charges processed outside of the United States.


  • Sign up bonus. $150 Reward Dollars (redeemable for a statement credit) is not the greatest sign up bonus ever, but it is still pretty nice easy money. The fact that the minimum spending requirement to earn the bonus is only $1,000 of spending in three months makes this offer even better.
  • High cash back. This card is the leader in providing cash back rewards on most common purchases such as those at US supermarkets, US gas stations, and select US department stores.
  • 0% intro APR. Get 0% on purchases and balance transfers for 15 months. (Then it goes to a variable rate, currently 12.99% to 21.99%, depending on creditworthiness and other factors.)
  • Reasonable annual fee. $75 is a significant annual fee, but considering that the cash back rewards are so high, it is not out of line with many leading reward cards.
  • Generous benefits. Like many American Express cards, this card offers great benefits for consumers like Return Protection and Extended Warranty. Plus, there's the Roadside Assistance Hotline, Car Rental Loss & Damage Insurance, Travel Accident Insurance, a Global Assist Hotline, and more.


  • Foreign transaction fees. Simply put, this fee is a complete rip-off. Many other banks are getting rid of these charges, but American Express continues to retain this fee on all but their Platinum and Centurion cards. Until they join the crowd and eliminate this fee, I will keep calling them out on it.
  • Mediocre interest rates. After the intro period, cardholders receive an APR of between 12.99% and 21.99%, depending on their credit worthiness. There are other cards with lower interest rates best suited to those who carry a balance.
  • Annual cash back limit. The 6% cash back at US supermarkets is only for the first $6,000 in purchases. After that, the cash back percentage drops to 1%.

Who This Card Is Best For

This card, like all reward cards, is not for those who carry a balance on their credit cards. If you do, you should focus on finding a low interest card and paying off your debt.

For everyone else, the key to this card is figuring out if you normally spend enough on the key cash back categories to easily justify the annual fee. For example, if you spend $50 per week at US supermarkets, or $2,600 per year, you will earn $156 of cash back each year. Those who spend $50 per week at US gas stations will earn $78 per year in cash back.

Note: If you do the math and come out way ahead, this might be the cash back card for you. But if the numbers don’t work, you might want to consider the "Everyday" version of this card, the Blue Cash Everyday Card® from American Express. Sure, the bonuses are less, but there is no annual fee.

Once you have considered how these cards will work for your budget, you can choose the card that will give you the most cash back in the end.

Although I am a Dave Ramsey follower, I won't give up this card for groceries and gas. With a family of 6, I've made over $500 in cash back this year, and will do even better next year, even with the cutoff coming. I pay it off weekly online.

I recently opened a Blue Cash Preferred AMEX account, and they offered me a 0% APR introductory rate for the first 12 months. Although there is an annual fee (which I usually don't like paying for), I feel like the perks you get from having the card more than pay for it (especially if you maximize the cash back).

I have been using the amex blue cash for several years now. I use it to pay for gas, groceries, restaurants & etc... As you mentioned in your post, Amex cards are really great for renting cars because their insurance policy is probably the best if something happened to your rental car.
