Happy Birthday to bizologie co-founder Laura Young! For the special day I thought I would cover the business of birthday cards. According to the Greeting Card Association, American’s spend $7.5 billion on greeting cards each year. Nine out of 10 U.S. households buy cards, with the average household purchasing 30 cards a year. Overall we purchase 7 billion cards. Sales are evenly split between seasonal and everyday cards. The most popular seasonal cards are Christmas and holiday cards, which account for more than 60% of all seasonal card sales, followed by Valentine’s Day, Mother’s Day, Father’s Day and Graduation cards. Everyday card top sellers are wedding/anniversary, get well/sympathy, and friendship/encouragement cards, but of course the most popular everyday cards are birthday cards which account for more than half of all the everyday card sales.
