Today is the last day to get a 0% APR for 15 months on purchases and a 0% balance transfer for 15 months for signing up for the Discover More Card. This allows you to transfer a balance from a higher-interest credit card and pay it off with no interest through late next year. You could also use it to make a big ticket (like a car or that 65" TV) and pay it off on the card interest free. You'll also get up to 5% cash back on all purchases made with the card. Note that there is a 3% fee applied to balance transfers, but there is no annual fee.
