Butlers, forced by billionaires to mash piles of fruit by hand, invented blenders to prevent carpal tunnel and subsequent demotion to human towel rack. Reap the benefits of their creation with today's Groupon: for $4, you get $8 worth of freshly squeezed juice and smoothies, sandwiches, and more at Tree City Juice and Smoothie Cafe. This Groupon can be redeemed at your choice of Tree City's downtown Boise or Meridian Crossroads locations.

Health-conscious consumers can seek refuge in Tree City's tempting list of juices and smoothies without sacrificing dessert-like decadence. Keep a bad day at work from overwhelming your stress nodules by bringing a laptop to Tree City, and surf the free WiFi while riding a refreshing wave of Go Orange!, a citrusy soiree of OJ, orange sorbetto, and nonfat frozen vanilla yogurt ("berries and more" smoothies start at $2.99). Power up before hitting and defeating the gym with a protein-packed Triple Berry Blast smoothie, loaded with blueberries, raspberries, cranberry juice, skim milk, nonfat vanilla frozen yogurt, honey, and whey protein ("power up" protein smoothies start at $3.59). Dairy-free, vegan-friendly sips are also available, ranging from simplistic shots of wheatgrass ($1.49 for 1 oz.) to fancy crazy-straw fillers like Gingerwocky juice, a fresh blend of apple juice, carrot, and ginger (juices start at $3.19). An extra dose of health can be added to your frosty treat for free with smoothie supplements such as smart blend, hangover recovery blends, energy-boosters, and more.

Keep your body's liquid content in check by introducing some solid sustenance, such as a toasty pesto-chicken panini ($4.59) or a tuna wrap with celery, spinach, and mozzarella ($4.09). Enjoy Tree City's outdoor seating until the mystical property of evaporation has transmuted your smoothie into a chewable state.
