Caribous are intelligent, beautiful, majestic creatures! They heard my call! While this classic free birthday drink has been around forever, it was originally only a free medium drink. After some mild complaining on my part, they upgraded it to any drink, any size. However, as of 2022, you must make at least 1 purchase in the previous 6 months in order to qualify for this annual birthday offer.
It's cool they offer the same promo as soon as you sign up! So after you make a single purchase, you get both a free drink now and a free drink on your birthday. Not bad!
