We’ve all been there. After spending hours trick-or-treating, you come up and go through your candy and realize that half of it is candy you don’t even want. Reese’s created a vending machine to combat this problem. The Candy Converter lets you trade unwanted, low-ranking candy for Reese’s Peanut Butter Cups.

The machine will be available from 4:00 p.m. to 9:00 p.m., or until its 10,000 Reese’s cups are all given out. It will be located at NYC’s Washington Square Park on 5th Avenue on Halloween night. First come, first serve.
