Valentine's Day
Anyone can receive a valentine!
Valentine's Day uses an apostrophe. However, most people just use the plural form valentines for cards.
According to the Greeting Cards association, approx. one billion Valentines Day Cards are sold each year. But today, with the increase on technology, e-cards are becoming more and more popular, so it is possible that that number has decreased slightly.
An average of 8/10 people will buy valentine cards every year.
