Cinemark will fill almost anything with popcorn this weekend—but there’s a catch

If you’re planning to hit up a movie over the long weekend, you’re in luck. Going to the theater will be a bit cheaper for two days, as long as you believe popcorn is a must-have movie accessory. 

That’s because Cinemark, in partnership with Lowes, is celebrating National Popcorn Day, which falls on Mon. Jan. 19, with a reprise of last year’s Bring Your Own Bucket (BYOB) event. To celebrate, select Cinemark theaters will let you bring a bucket (any bucket) to fill to the brim on the 18th and 19th for just five bucks.
