These cards have 0% interest on new purchases for an introductory period for 12 months or more. This will enable you to make large purchases on items such as a car or new television and then pay off the credit over the course of a year without paying interest on those purchases
This makes a 0% purchase credit card the best choice for you if you are planning on using the card frequently for shopping. These cards essentially allow you to borrow for free as long as you pay off the debt before the interest free period ends, making them one of the most cost effective ways to borrow money.
