Earn 2% cash rewards at grocery stores and Costco

The Wells Fargo Active Cash® Card(Rates and fees) is a powerful rewards card that allows you to earn unlimited 2% cash rewards on purchases — including on groceries, even at warehouse stores like Costco.

New cardholders can also earn a one-time cash rewards bonus — $200 cash rewards bonus after spending $500 in purchases in the first 3 months!

If you’re looking for a powerful rewards card that offers an extended intro APR period, look no further, the Wells Fargo Active Cash® Card checks that box too!

This card also offers an intro APR of 0% for 15 months from account opening on purchases and qualifying balance transfers (then 20.24%, 25.24%, or 29.99% Variable). Which is great for someone who wants a break from high interest rates, while still earning rewards.

The best part? There's no annual fee.
