Sign up for a 28-Day Auto-Delivery Plan at Nutrisystem and get One Free "Fast 5" Week with your first order, which includes 7 Craving Crusher shakes, 7 EnergiZING shakes, and 7 breakfasts, lunches and dinners designed to take off 5 pounds in the first week (individual results vary). Plus, shipping is free. Plans start at $8.21 per day for the Women's Basic plan, discounted from $11. Signing up for this Nutrisystem Auto-Delivery Plan gets you convenient automatic billing every 28 days. The fine print states that you'll need to spend two 28-day cycles in the Auto-Delivery program before canceling, or be charged the non-discounted price for month #1. Nutrisystem D program is excluded from this promotion. Sales tax is charged in most states.
