Before the invention of the blender, vitamin-seekers experimented with ways of attaining power-packed doses of nutrients, such as cramming mouths with mixed berries while rolling down hills or chewing on miniature portraits of fruit bowls. Experience fruit fusion without the bellyache with today's Groupon: for $10, you get a punch card good for three large smoothies at Jamba Juice (up to a $21.18 value). This Groupon is only valid at Jamba Juice's Pittsburgh location.

The smoothie engineers at Jamba Juice soak torrid tongues with delicious nutrient-rich concoctions from an extensive menu void of artificial preservatives or trans fats. Each large smoothie (a $7.06 value after tax) packs a vitamin wallop that helps people to lead healthy lives and gives them enough energy for all of life’s challenges, from getting through the workday to jumping safely from a cellular tower into a nearby kiddie pool. Take tongues for a whirl with the Strawberry Surf Rider, a smoothie made with strawberries, peaches, Jamba lemonade, and lime sherbet, or pump your palate with a Peach Pleasure smoothie concocted from peach, banana, and orange flavors. Fruit-and-veggie blends, such as the Apple 'n Greens or the Orange Carrot Karma, fuse the salubrious benefits of both types of soil-sprouters in a frozen treat that's more enjoyable than devouring a still-life painting.

Like the legendary smoothie chambers of Greek mythology, the frozen drink shop is clean and bright and staffed by friendly juicefolk accustomed to satisfying the most outlandish smoothie fantasies. Whether you're a smoothie fanatic driven to smoothie slurping or just want to forgo air conditioning in favor of a tall, cold drink pressed against your forehead, Jamba Juice’s sippable yum delivers well-blended liquid satisfaction.
