I've read several sites today that talk about this $5 off of $5 purchase at Hallmark stores. Some people were questioning the validity, but two different sites say they've emailed the PR people at Hallmark who emailed them links to the coupon. So it does seem to be valid. Just click on the "click to print" button on this page. The coupon is good 12/3 to 12/5.
ALSO if you're one of the first 5 people through the door (it's supposed to be kids, but adults are being able to do it also) to say the magic phrase “Are you a friend of Kromdar the Magnificent?” you can receive a free freaky pet as pictured here. This is only good through 12/3 so hurry in today!!
Not all Hallmark stores carry the Freaky Pets, so if you want to check before you go, you can input your zip code here to check out your own store.
