How many St. Patrick's Day cards does Hallmark sell?

In 2014, the Hallmark greeting card company offered its customers more than 100 different St. Patrick's Day cards, including specialized birthday cards for those who were born on March 17. Though St. Patrick's Day may not necessarily be the holiday that is most closely associated with greeting cards, Hallmark has been producing cards for this holiday since 1920.

Though greeting cards aren't a major St. Patrick's Day tradition, they are a part of the wide range of product offerings that entice Americans to spend upwards of $4.5 billion dollars during the process of celebrating this holiday. Hallmark's St. Patrick's Day cards tend to range in price from about $1 to $5.
