<prompt> Human: My fiance and I are looking into getting a credit card that offers a rewards program, preferably a cash back one. Our idea is to pay all the bills on the credit card each month and then just pay the credit card bill off completely at the end of the month to earn the rewards. The card would only be used for that purpose. My question is...what is the best card out there? Which one would yall recommend?  <response>: NerdWallets compare tool will help you out - type in how you spend your money, and it finds the best rewards cards for you.
