I don’t know how long this is going to last, but if you know the secret code you can go to the Hallmark web site and personalize a paper card for your mom. Hallmark will even send it out free of charge, and that includes the postage. These cards are good looking and allow you to add a personal message and get it there before the holiday.
1) Go to Hallmark.com
2) Register as a user
3) Select the Mother’s Day car you want to send
4) Personalize it
5) Address it
6) When checking out use the promotional code: CARD4MOM
I just did this myself and it says I owe nothing and the card will arrive within days.
