Walmart offers this Personalized "I Love You This Much" Wood Postcard for $17.99. Choose in-store pickup to avoid the $5.99 shipping fee. It's $2 off and the lowest price we could find. It measures 6" x 3-3/4" and can be personalized with any 2-line message up to 30 characters. It's also guaranteed to last longer than a standard paper Valentine -- unless your sweetheart is a woodchuck. We don't judge.
