Stock up on Hallmark cards at Walgreens! This week, buy three Hallmark cards and receive 3,000 Balance Rewards Points, later worth $3.00. At my store, I found gift card and money holder Christmas cards priced at only $0.99 and included in the promotion. Buy three cards and pay $2.97. In return, receive 3,000 Balance Rewards Points. You just got yourself three cards for better than free!
