These $5 off $5 Hallmark coupons were available in several magazines recently. If you don't happen to get any of the magazines that included the coupon you can now print two from the Hallmark website.
To get the most out of a coupon like this spend just over $5. Unless, of course, there is something you were going to be getting at Hallmark anyway. To use both coupons, you'll have to do two separate transactions.
Things are pretty pricey at Hallmark, but I'm guessing you can at least get something for free with this coupon.
