Well,generally Coupons get shipped in the mail. But for a limited time we were giving them out in each bag that has since ended. (I say "we" because I work at bk) Although there are many good deals out right now like: a 10pc nugget for $1.49 also we have the 2 for $5 on the following: Big king,Original Chicken,Big fish,extra long cheeseburger, and the NEW flame grilled chicken burger.
Soon though, starting on Jan 6th. We are getting a 5 for $4 deal which include: a bacon cheeseburger,small fry,small drink,4pc nugget and a cookie.
of course these deals are subject to change and are only valid in the U.S. and also may differ from state to state but that is the general deals for bk at this time. I hope I was helpful. :)
