Burger King created a campaign based off of a funny and on-point insight: people receive a lot of unwanted gifts during Christmas season. By allowing their costumers to donate their presents to those actually in need in exchange for a Whopper, BK turns this campaign into something wholesome (in the Holiday spirit).
