The promo also touches on the chain's origins, when the Colonel first opened up shop in the front room of a filling station in Corbin, Kentucky.

Never mind that $5 back then would be the equivalent of about $67 today.
Regardless, KFC Fill Up meals are one of the chain's better value meals in recent times. You can read more about them here.
