Reese's has created a candy converter that exchanges unwanted candy for Reese's Peanut Butter Cups.

Starting at 4 p.m. today, the bright orange vending machine will be set outside Washington Square Park on 5th Avenue in New York for trick or treating. The vending machine made its first appearance Oct. 28 at a Halloween parade in Tarrytown, New York.
