Halloween Candy Prices Are Scary High: This is enough to make you scream in terror. The cost of Halloween candy is up 13 percent this year. That's according to the U.S. Bureau of Labor Statistics and a UCLA supply-chain expert. They note that candy is more expensive due to the rising costs of ingredients and labor. The average U.S. household is expected to spend about 35 dollars on candy this year, up from 30 dollars in years past. The price of candy and gum has jumped two percent since August which is a near-record increase.
