<prompt> Human: Im looking to start using a credit card for all of my monthly purchases Utilities, Groceries, Mortgage if possible, etc to get the rewards, and then paying it off monthly to avoid any interest charges. Im sure a lot of you do this, does anyone have any suggestions on finding the best cards I should use? Anyone use a card they are really happy with? Edit: Im American and I have pretty good Credit 720-750.  <response>: Come join us over at rchurning
