Feeling that 2 p.m. slump and need a boost? From today through Wednesday, March 30, selected Jamba Juice stores are offering two 16-oz. smoothies, juices, Ideal Meals, or hot blends for only five bucks. While normally a 16-oz. smoothie runs for $3 to $4 plus tax, you can get in with a co-worker or friend and save a few dollars for an afternoon pick-me-up. Instead of that costly caffeine fix, resurge your body with a cold fruity blend and add in an energy boost for productive work flow. For healthier options, don't forget to try the chain's new Fruit and Veggie smoothies. You must bring in this coupon for the offer to apply.
