"The more you know about credit cards, the better equipped you'll be to make choices that work out in your favor – whether you're taking advantage of your credit card grace period to avoid interest charges, using a 0% intro APR credit card to fund a vacation or redeeming your credit card rewards at their maximum value. Credit is a powerful tool, when used wisely – and as a person who's been writing about personal finance for a decade, I hope to provide you with the tools to make as many wise decisions as possible."
