Before responding to any credit card offers, you should know that not all terms are included in the initial offer. The most important information is found only in the “Cardholder Agreement” usually being sent along with the new credit card. It is a legal contract between you and the card-issuing company, all together making up the contract for transactions on your card account. Once you use the card, it binds you to honor what has been stipulated in the agreement and that can change at any time.
