Chocolate crunch: Hershey says it won't be able to meet Halloween demand this year

This Halloween may bring more tricks than treats, with candy maker Hershey warning on Thursday that it won't be able to meet consumer demand for the October 31 holiday. 

CEO Michele Buck warned about the potential shortfall on the company's second-quarter earnings call, noting that while seasonal consumer demand remains high, "We will not be able to fully meet consumer demand due to capacity constraints."

That means Halloween favorites such as Reese's Peanut Butter Cups, Kit Kat, Mr. Goodbar and Almond Joy may not be as plentiful this Halloween as in previous years.
