That is a place that you can put in the coupon codes that your Health Advisor passes to you, when you are able to use one
For example, when you place your first order through Take Shape for Life (with your health advisor's help) Medifast and your HA have a coupon code that they can put in there to give you.
I hope this helps. Talk to your Health Advisor and they can help you out on that as well.
