You can print a coupon for $1.00/2 American Greetings cards right here (note that as soon as you click this link, your coupon will begin to print).
Check out your store’s $0.99 section and you might find some there making for some inexpensive cards. Even if you have no occasion to buy for now, it is always helpful to have a couple on hand (I usually always grab a sympathy or congrats card in this case).
