First glance, this looks like a cute cupcake birthday card. Nothing more. But I'm so wrong.
American Greetings has introduced a new concept for greeting cards. Tasties, as they are called, come with a dissolvable flavor-strip sealed inside the card. Each card has a different flavor-strip that corresponds with the card. The flavors range from donuts to margaritas. This birthday card encourages the recipient to eat cake and the flavor-strip included tastes like a vanilla cupcake.
Fun idea! The greeting card industry is definitely in need of something to persuade people to buy greeting cards again. This might do the trick.
