Thirsty Thursday, indeed!
Jamba Juice is offering an upsize on any smoothie, every single Thursday in May…and there’s only a few left!
Each Thursday during the month of May you can upgrade your medium Jamba Juice to a large size for no extra cost (and that’s a 99-cent value).
This “Thirsty Thursday” upgrade is available at U.S. participating Jamba Juice locations only. Enter your zip code to find a Jamba Juice near you!
