I just got an email with a coupon for a free Hallmark Card when you buy a Hallmark card (up to $2.50). So if that interests you, you might want to check your email. If you don't get emails from Hallmark and want to, well go to their site and sign up! Duh!
I have a little hint for you though: Cards are only .50 cents each at the Dollar Tree. Holla For the Dolla!
