KFC is doing holiday packaging , which means it is joining a mistletoe parade that includes the contentious non-sectarian Starbucks cup and Dunkin’ Donuts. The KFC Holiday Bucket is a limited-time serving container for the $20 Family Fill special, which the company says will serve a family of four. Dunkin’ offered a cursive “Joy” on the brand’s holiday cups as well as incentivized social-media shares of the container.
