Save money on Valentine's Day cards this year by printing out this coupon from American Greetings. "Like" them on Facebook and then click on their "Val Day" tab to print your coupon. Up to two coupons allowed per computer; just hit your back button after the first one is printed to get a second coupon.
Note: This coupon excludes Valentine's Day cards priced at $0.99. But, it should make for one free card if you can locate two cards priced under $2 (which isn't very hard to do at all).
