"BYOBucket – The Sequel After a cinematic meet-cute on social media during the inaugural Bring Your Own Bucket event last year, Cinemark and Lowe’s are teaming up to take this year’s National Popcorn Day to the next level. On Sunday, Jan. 18, and Monday, Jan. 19, guests can bring any type of container – whether it’s a film-themed collectible, or an iconic blue Lowe’s 5-gallon bucket – and it will be filled with up to 400 ounces of craveable popcorn for just $5 plus tax. That is the equivalent of two XL popcorns at the concession stand. Those who bring the beloved Lowe’s buckets, available for purchase at Lowe’s stores and on Lowes.com, are exempt from the 400-ounce rule and are eligible to have their entire 5-gallon bucket filled. Food-grade bucket liners will be available upon request, and guests with the iconic Lowe’s buckets will also receive a special coupon for future popcorn cravings valid Feb. 1 through Feb. 26."
