Several credit cards offer 0% interest on purchases for some period of time and then for some fee or higher interest rate later. Have a look at our credit card comparison table for an overview of the current deals on the market.
Credit cards that offer 0% interest on purchases should be used, as with all plastic, with care. If you have some significant purchases to make in a short period of time, and if you're able to pay them off before the 0% interest expires, then a card with 0% interest on purchases may be a good option. If you cannot pay off the entire balance within that 0% interest period, then it is probably not a good option for you. Constantly changing credit cards in order to transfer balances, and so amassing credit cards, is not good for your credit score. This can be done advantageously, but seldom.
With the current financial situation in the U.S. and the U.K., however, these deals are becoming more difficult to find. Creditors are cracking down on those that already have cards with balances, as well as making it difficult on those who are not yet their customers. As with everything financial, do your homework. Only take on what you can honestly afford to deal with, get all of the terms in writing, understand the terms, and take advantage of good offers.
