I can't help but love the "Reese's Halloween Candy Converter." It's a vending machine where some fortunate trick-or-treaters can feed their unwanted Halloween candy (cough *Good & Plenty*) to get a Reese's Peanut Butter Cup in exchange. Now that's a clever marketing stunt!
There's only one machine though and it's in New York City:
Reese’s lovers can make an exchange from 4 p.m. to 9 p.m. outside Washington Square Park on 5th Avenue between Washington Square North and East 8th Street in New York City on Halloween.
Delish reports that the machine will make 10,000 candy exchanges.
