Join their free Crown Rewards program and you'll get a free Hallmark Card in-store each month through December 31! Each card is worth up to $3.99, so this entire offer is valued around $48.
To redeem this, simply use the coupon they email you or login to your account and look under Hallmark Offers.
This offer previously expired in June 2021, but it was so popular that they extended it throughout 2022. That gives us 18 extra freebies!
