The Discover More Card doesn't offer the best rewards program on the market. It also doesn't offer the longest 0% interest promotional period. So why would anyone want to get it, and what makes it Discover's flagship card? What the Discover More Card consistently offers cardholders is a little bit of everything in one package. No annual fee, 0% interest on both purchases and balance transfers, and a cash back program that provides up to a 5% bonus for certain categories throughout the entire year. In addition, Discover doesn't mess around with the card's benefits very often, so consumers have come to know and understand what they can expect from this card.
