Reader Andrea passed along a great coupon that is available from Hallmark . It appears to be for new moms or those that are expecting- you just register to receive emails from Hallmark and then you can choose either a $10 off $10 purchase coupon or a 25% off for Hallmark.com.
The coupon does say participating Gold Crown stores only so there is a chance some stores will refuse your coupon.
UPDATE: My coupon did print with a valid bar code. If your coupon does not have a bar code- it is not a valid coupon.
