To celebrate Halloween, you can get a great Caribou Coffee coupon, valid today only: buy one drink, get one FREE! The free drink must be of equal or lesser value. You can get hot or cold beverages with this coupon. I’ll be getting a hot beverage this afternoon; it’s freezing in Minnesota!
You don’t even have to print this coupon if you don’t want to. They will accept it right from your mobile device. This offer is limited to one per person, and is valid today only.
