Many couples also celebrate by seeing a show or going out to a restaurant. And yes, that even includes Valentine's Day dinner at White Castle.
2. Greeting Cards
According to the Greeting Card Association, 145 million cards are exchanged each Valentine's Day, and that's not counting all the valentines kids get at school.
1. Candy (specifically chocolate)
The National Confectioners Association says as many as 40 million heart-shaped boxes of chocolate are sold each year.
When it comes to chocolate, caramel-filled treats are the most coveted, followed by chocolate-covered nuts. Also popular are chocolate- and cream-filled chocolates.
Conversation hearts are also a longstanding Valentine's Day tradition. Necco produces 8 billion hearts each year, and the association says that's enough to stretch from Rome to the town of Valentine, Arizona, and back almost two dozen times.
