When you get a Discover card, you’re allowed to choose from over one hundred fifty designs, and you can order a new card with a different design at your leisure. I think it’s a brilliant marketing move. When you choose a new card design, it gets you excited about using your Discover card again. You want to pull out your card with puppies on it, or palm trees, or the Statue of Liberty, so that clerks everywhere will say, “Ooh, what a cool credit card you have.” And then, as if getting you to use your card more wasn’t enough, it might also convince others who see it that they should get a Discover card. That way they can have a credit card with puppies on it.
