The beauty of a cash back credit card is that you get cold hard statement credits rather than the sometimes confusing reward point system.
The American Express Blue Cash Preferred offers the following:
6% cash back at supermarkets. An average two person household will spend about $7,000 a year on groceries and this card will get you 6% cash back on your first $6,000 (that’s $360 cash back!) then drop to 1% cash back afterwards.
One more thing to keep in mind is that the average “supermarket” sells a lot of gift cards from restaurants and other retailers such as Amazon and Apple! This is a great hack to maximize the 6% cash back.
3% cash back at gas stations. Note that this 3% cash back only applies to gasoline purchased at gas stations.
1% cash back on all other purchases. 1% cash back is pretty mediocre so we would suggest using another cash back credit card for purchases that don’t fall within the supermarket or gas station category.
