What’s a trip to the movie theatre without buying one of those buckets of popcorn, and spending 10 bucks for it? Coming on January 19th, you get a major break on those popcorn prices and you can bring your very own bucket to any Cinemark.

That's the gambit of a new promotion Cinemark locations are rolling out later this month in which the theater chain will allow fans to BYOB. That second B though isn't "beer," it's for "bucket" - specifically a popcorn bucket.

The Cinemark movie chain plans to serve up a massive amount of buttery goodness during National Popcorn Day in January.

In honor of National Popcorn Day, Cinemark is letting you bring your own personal bucket to fill up with popcorn. But there's a catch.
