I love it because it's SIMPLE! It's as easy as setting a 90 day goal and choosing which of the four ViSalus Body by Vi™ Challenge Kits fits with your goal...then let the products do the rest! Because each kit centers around the Vi-Shape meal replacement shake, we won't be adding any additional cost to our budgets. We're simply taking the money we currently spend on eating out and grocery bills and putting it toward a simpler, faster, and much healthier option! The success stories I have seen so far are amazing! On top of saving money on food bills, they have a program called Refer 3, Get Your Next Month Free! Simply refer three others to the same or greater Challenge Kit as you, and they'll ship your next kit for free! Maintain 3, and your products are always FREE!
