(CNN) – It's Halloween and for many retailers, business is boo-ming.
Average spending may be down a bit from last year, but consumers are still expected to spend about $6.9 billion on all things sweet and scary.
Here are some things you might not know about the business side of Halloween.
First, the average Dracula is expected to spend about $75 on the holiday. That includes money for decorations, costumes, candy and having some fun, according to the National Retail Federation.
All the fake spider webs and tombstones add up. If you break down decorations alone, retailers estimate that the average person will spend $21 on them.
That makes Halloween second only to the Christmas season.
The candy of choice? According to a national confectioner's association survey, 72 percent of people want to sink their fangs in chocolate.
Chocolate makes up about three-quarters of a trick-or-treater's candy bag, which makes cavities excited, too.
In second place in the candy market is the time-honored fall classic, candy corn. It's the sweetest corn.
The tri-colored confection was invented in the 1880s.
What is now the Jelly Belly Candy Company has made it pretty much the same way since 1900, using mostly sugar, corn syrup, and marshmallow.
Here's an odd fact, though: Some think there's a "right way" to eat candy corn.
Of those surveyed, 47 percent said to eat the whole thing at once, while 43 percent said to start with the narrow, white end first. Only 10 percent said to start with the wide, yellow part.
After decorations and candy come costumes.
Consumers will shell out $2.6 billion on costumes this year.
Over all, witches and Batman seem to be most in demand for adults, while kids often plan to dress as princesses, animals or Batman. So Batman forever.
And this is kind of scary: a good chunk of what consumers spend will be on consumes for their pets.
Retailers expect that humans will spend $330 million to totally humiliate Fido and Fluffy for their furry photo-ops.
Awkward pet photos or first world problems? Either way, it's frightening.
