Get 40% off when you sign up for the 28-day auto delivery program at Nutrisystem. Plus, you'll get one week of food for free! For example, the Women's Core Program, which retails for $412.45, is going for $244.99, which is $25 under the price we saw for this plan in June. It includes 28 days of breakfast, protein shake, lunch, dinner, and dessert with free shipping delivered to your door. Note: the deal is only on their auto-delivery plans, so the plan will be renewed unless you cancel the subscription. Sales tax is charged in most states.
