Your Valentine's Day IQ: Answer 4
 If you answered Mother's Day, you're WRONG!

It's answer A:  Christmas is the only holiday that can top Valentine’s Day in terms of cards purchased. An estimated 2.6 billion cards are sent each year for Christmas, reports the Greeting Card Association. Valentine’s Day is a distant second with 1 billion cards sent annually.  Long considered the fairer, more romantic sex, women purchase approximately 85 percent of all valentines. There is no data, however, on the number of forgetful husbands forced to sleep on the couch Valentine’s night.
