0% credit card balance transfer

I've finally settled most of my outstanding payments on the oh-so-many credit cards that i own. Most of them have recurring payments on them to keep the card running. But the peril lies when i forget to make my repayment on time. That's when interest starts to accumulate. Apart from that, doesnt look good on my credit history also.

My friend has just switched to the new Mint credit card. Says it now offers a 14.9% APR. How nice. All mine are at 18% APR. And also, it offers 0% on purchases until 1 January 2008, 0% on credit card balance transfer until 1 August 2008 with a 2.5% balance transfer fee. I also carried out a credit card balance transfer on one of my cards to save on interest. But the 0% only lasts 3 months.
