If there's one thing we all do, it's buy groceries. My household spends close to $1,000 a month feeding two adults and two kids. But you only need to spend half that amount to unlock the full grocery cash back benefit from this credit card.

With the Blue Cash Preferred® Card from American Express, you can earn 6% cash back at U.S. supermarkets (up to $6,000 per year in purchases) and select U.S. streaming subscriptions. Terms apply. That adds up to $360 in rewards every single year, just for buying your usual groceries.

Here's what you need to know.

Max out grocery rewards up to $360 per year

The Amex Blue Cash Preferred is one of the best gas and grocery rewards cards available. This card gives you 6% cash back at U.S. supermarkets (up to $6,000 per year in purchases) and select U.S. streaming subscriptions. After that, you still earn 1% cash back. Terms apply.

Here's a quick breakdown of potential rewards, based on different spending levels:

Quick heads up: Superstores like Walmart and Target don't qualify for the 6% grocery category. So if most of your food shopping happens there, you may want to explore other rewards credit cards.

But if you spend around $500 a month at eligible supermarkets, you could earn up to $360 back every year -- without even changing your routine.

Other cash back categories

This Amex card offers strong everyday cash back in other categories, too. Here's the full list of cash back earning opportunities with the Amex Blue Cash Preferred:

• 6% cash back at U.S. supermarkets (up to $6,000 per year in purchases) and select U.S. streaming subscriptions
• 3% cash back at U.S. gas stations and transit (including taxis/rideshare, parking, tolls, trains, buses and more)
• 1% cash back on other purchases
• Terms apply

If you're commuting, streaming, or road-tripping often, the extra cash back can really add up. For example, when my family drives to Montana each summer, we spend about $600 on gas. At 3% back, that's $18 in rewards -- enough to refuel with snacks for the road.

This card has a $0 intro annual fee for the first year, then $95. (See rates and fees.) This makes it easy to test the card's value without risk.

Earn a $250 welcome bonus

New cardholders can also grab a $250 welcome offer after spending $3,000 in the first 6 months. Terms apply. That's a super attainable bonus.

If you're planning a back-to-school stock-up or just have consistent grocery bills, you could reach that threshold quickly.

Is the Amex Blue Cash Preferred right for you?

The Blue Cash Preferred® Card from American Express makes the most sense for people who regularly shop at U.S. supermarkets and use streaming services. It's especially strong for families or anyone spending $400+ per month on groceries. Just make sure to pay your balance in full each month to avoid interest.
