I buy my cards at Dollar Tree, 2/$1.00. A birthday card really make a person feel special, to know you took the time to remember and send the card. I send a lot of birthday cards, makes me as happy as the person receiving the card. I make a list of the next months birthdays, shop for them, address and get them ready to go then put in the corner where the stamp goes the date I need to put it in the mail box. My system works good for me. FYI- My dollar tree is now carrying Hallmark cards in their 2/$1.00 line.
