Taco Bell is using the World Series as an excuse to give away free food again. The campaign Steal A Base, Steal A Taco is back. Here’s how it works: when any MLB player steals a base during the World Series, Taco Bell customers can get a free taco. This year you can choose from a Nacho Cheese shell, a Fiery shell, or a Cool Ranch shell for your free taco. The deal is valid for customers who visit any Taco Bell store on November 1st, from 2 p.m. to 6 p.m., after all series games have been played.
